NAME
       muttrc - Configuration file for the Mutt Mail User Agent

DESCRIPTION
       A  mutt  configuration  file  consists of a series of "commands".  Each
       line of the file may contain one or more commands.  When multiple  com-
       mands are used, they must be separated by a semicolon (";").

       The  hash  mark, or pound sign ("#"), is used as a "comment" character.
       You can use it to annotate your initialization file. All text after the
       comment character to the end of the line is ignored.

       Single  quotes  ("'")  and  double  quotes  (""")  can be used to quote
       strings which contain spaces or other special characters.  The  differ-
       ence between the two types of quotes is similar to that of many popular
       shell programs, namely that a single quote is used to specify a literal
       string (one that is not interpreted for shell variables or quoting with
       a backslash [see next  paragraph]),  while  double  quotes  indicate  a
       string for which should be evaluated.  For example, backtics are evalu-
       ated inside of double quotes, but not for single quotes.

       \ quotes the next character, just as in shells such as  bash  and  zsh.
       For  example,  if  want to put quotes (""") inside of a string, you can
       use "\" to force the next character to be a literal instead  of  inter-
       preted character.

       "\\"  means  to insert a literal "\" into the line.  "\n" and "\r" have
       their usual C meanings of linefeed and carriage-return, respectively.

       A "\" at the end of a line can be used to split commands over  multiple
       lines,  provided  that  the  split points don't appear in the middle of
       command names.

       It is also possible to substitute the output of a Unix  command  in  an
       initialization  file.  This is accomplished by enclosing the command in
       backquotes (`command`).

       UNIX environments can be accessed like the way it  is  done  in  shells
       like sh and bash: Prepend the name of the environment by a dollar ("$")
       sign.


COMMANDS
       alias key address [, address [ ... ]]
       unalias [ *  | key ]

              alias defines an alias key for  the  given  addresses.   unalias
              removes  the alias corresponding to the given key or all aliases
              when "*" is used as an argument.

       alternative_order type[/subtype] [ ... ]
              This command permits you to define an order of preference  which
              is  used by mutt to determine which part of a multipart/alterna-
              tive body to display.  A subtype of "*" matches any subtype,  as
              does an empty subtype.

       auto_view type[/subtype] [ ... ]
              This  commands permits you to specify that mutt should automati-
              cally convert the given MIME types to text/plain when displaying
              messages.   For  this  to work, there must be a mailcap(5) entry
              for the given MIME type with the copiousoutput flag set.  A sub-
              type of "*" matches any subtype, as does an empty subtype.

       bind map key function
              This  command binds the given key for the given map to the given
              function.

              Valid maps are: generic, alias, attach, browser, editor,  index,
              compose, pager, pgp, postpone, mix.

              For  more  information on keys and functions, please consult the
              Mutt Manual.

       account-hook [!]regexp command
              This hook is executed whenever you access a remote mailbox. Use-
              ful  to  adjust  configuration settings to different IMAP or POP
              servers.

       charset-hook alias charset
              This command defines an alias for a character set.  This is use-
              ful to properly display messages which are tagged with a charac-
              ter set name not known to mutt.

       iconv-hook charset local-charset
              This command defines a system-specific name for a character set.
              This  is  useful when your system's iconv(3) implementation does
              not understand MIME character set names  (such  as  iso-8859-1),
              but  instead  insists  on being fed with implementation-specific
              character set names (such as 8859-1).  In  this  specific  case,
              you'd put this into your configuration file:

              iconv-hook iso-8859-1 8859-1

       message-hook [!]pattern command
              Before  mutt  displays (or formats for replying or forwarding) a
              message which matches the given pattern (or, when it is preceded
              by  an  exclamation mark, does not match the pattern), the given
              command is executed.  When multiple  message-hooks  match,  they
              are  executed  in  the order in which they occur in the configu-
              ration file.

       folder-hook [!]regexp command
              When mutt enters a folder which matches regexp (or, when  regexp
              is  preceded by an exclamation mark, does not match regexp), the
              given command is executed.

              When several folder-hooks match a given mail  folder,  they  are
              executed in the order given in the configuration file.

       macro map key sequence [ description ]
              This  command  binds the given sequence of keys to the given key
              in the given map.  For valid maps, see bind.

       color object foreground background [  regexp ]
       color index foreground background [  pattern ]
       uncolor index pattern [ pattern ... ]

              If your terminal supports color, these commands can be  used  to
              assign  foreground/backgound  combinations  to  certain objects.
              Valid objects are: attachment, body, bold,  header,  hdrdefault,
              index,  indicator,  markers,  message,  normal, quoted, quotedN,
              search, signature, status, tilde, tree, underline.  The body and
              header objects allow you to restrict the colorization to a regu-
              lar expression.  The index object permits you to select  colored
              messages by pattern.

              Valid  colors include: white, black, green, magenta, blue, cyan,
              yellow, red, default, colorN.

       mono object attribute [ regexp ]
       mono index attribute [ pattern ]

              For terminals which don't support color, you  can  still  assign
              attributes  to  objects.   Valid attributes include: none, bold,
              underline, reverse, and standout.

       [un]ignore pattern [ pattern ... ]
              The ignore command permits you to specify  header  fields  which
              you  usually  don't  wish  to  see.   Any header field whose tag
              begins with an "ignored" pattern will be ignored.

              The unignore command permits you to define exceptions  from  the
              above mentioned list of ignored headers.

       lists address [ address ... ]
       unlists address [ address ... ]
       subscribe address [ address ... ]
       unsubscribe address [ address ... ]

              Mutt  maintains  two  lists of mailing list addresses, a list of
              subscribed mailing lists, and a list  of  known  mailing  lists.
              All  subscribed mailing lists are known.  A mail address matches
              a mailing list if it begins with the given address.   For  exam-
              ple,  the lists pattern "mutt-" will match mutt-dev@mutt.org and
              mutt-users@mutt.org.

              The lists command adds a mailing list address  to  the  list  of
              known mailing lists.  The unlists command removes a mailing list
              from the lists of known and subscribed mailing lists.  The  sub-
              scribe  command  adds  a  mailing list to the lists of known and
              subscribed mailing lists.  The unsubscribe  command  removes  it
              from the list of subscribed mailing lists.

       mbox-hook [!]pattern mailbox
              When  mutt changes to a mail folder which matches pattern, mail-
              box will be used as the "mbox" folder, i.e., read messages  will
              be moved to that folder when the mail folder is left.

              The first matchig mbox-hook applies.

       mailboxes filename [ filename ... ]
              This  command specifies folders which can receive mail and which
              will be checked for new messages.  When changing folders, press-
              ing space will cycle through folders with new mail.

       my_hdr string
       unmy_hdr field

              Using  my_hdr, you can define headers which will be added to the
              messages you compose.  unmy_hdr  will  remove  the  given  user-
              defined headers.

       hdr_order header1 header2 [ ... ]
              With  this  command, you can specify an order in which mutt will
              attempt to present headers to you when viewing messages.

       save-hook [!]pattern filename
              When a message matches pattern, the default file name when  sav-
              ing it will be the given filename.

       fcc-hook [!]pattern filename
              When  an outgoing message matches pattern, the default file name
              for storing a copy (fcc) will be the given filename.

       fcc-save-hook [!]pattern filename
              This command is an abbreviation for identical fcc-hook and save-
              hook commands.

       send-hook [!]pattern command
              When  composing a message matching pattern, command is executed.
              When multiple send-hooks match, they are executed in  the  order
              in which they occur in the configuration file.

       pgp-hook pattern key-id
              The  pgp-hook command provides a method by which you can specify
              the ID of the public key to be used when encrypting messages  to
              a certain recipient.

       push string
              This command adds the named string to the keyboard buffer.

       set [no|inv]variable[=value] [ ... ]
       toggle variable [ ... ]
       unset variable [ ... ]
       reset variable [ ... ]

              These  commands  are  used  to  set and manipulate configuration
              varibles.

              Mutt knows four  basic  types  of  variables:  boolean,  number,
              string  and  quadoption.   Boolean  variables can be set (true),
              unset (false), or toggled. Number variables can  be  assigned  a
              positive integer value.

              String  variables consist of any number of printable characters.
              Strings must be enclosed in quotes if  they  contain  spaces  or
              tabs.   You  may also use the "C" escape sequences \n and \t for
              newline and tab, respectively.

              Quadoption variables are used to control whether or  not  to  be
              prompted for certain actions, or to specify a default action.  A
              value of yes will cause the action to be carried  out  automati-
              cally  as if you had answered yes to the question.  Similarly, a
              value of no will cause the the action to be carried  out  as  if
              you  had  answered  "no." A value of ask-yes will cause a prompt
              with a default answer of "yes" and ask-no will provide a default
              answer of "no."

              The reset command resets all given variables to the compile time
              defaults.  If you reset the special variabe all,  all  variables
              will reset to their system defaults.

       source filename
              The given file will be evaluated as a configuration file.

       unhook [ *  | hook-type ]
              This command will remove all hooks of a given type, or all hooks
              when "*" is used as an argument.  hook-type can be  any  of  the
              -hook commands documented above.

PATTERNS
       In  various places with mutt, including some of the abovementioned hook
       commands, you can specify patterns to match messages.

   Constructing Patterns
       A simple pattern consists of an operator of the form "~character", pos-
       sibly  followed  by a parameter against which mutt is supposed to match
       the object specified by this operator.  (For a list of  operators,  see
       below.)

       With some of these operators, the object to be matched consists of sev-
       eral e-mail addresses.  In these cases, the object  is  matched  if  at
       least  one  of  these  e-mail  addresses matches. You can prepend a hat
       ("^") character to such a pattern to indicate that all  addresses  must
       match in order to match the object.

       You  can  construct  complex patterns by combining simple patterns with
       logical operators.  Logical AND is specified  by  simply  concatenating
       two  simple patterns, for instance "~C mutt-dev ~s bug".  Logical OR is
       specified by inserting a vertical bar ("|") between two  patterns,  for
       instance  "~C  mutt-dev | ~s bug".  Additionally, you can negate a pat-
       tern by prepending a bang ("!") character.  For logical  grouping,  use
       braces ("()"). Example: "!(~t mutt|~c mutt) ~f elkins".

   Simple Patterns
       Mutt understands the following simple patterns:


       ~A           all messages
       ~b EXPR      messages which contain EXPR in the message body
       ~B EXPR      messages which contain EXPR in the whole message
       ~c EXPR      messages carbon-copied to EXPR
       ~C EXPR      message is either to: or cc: EXPR
       ~D           deleted messages
       ~d MIN-MAX   messages with "date-sent" in a Date range
       ~E           expired messages
       ~e EXPR      message which contains EXPR in the "Sender" field
       ~F           flagged messages
       ~f EXPR      messages originating from EXPR
       ~g           PGP signed messages
       ~G           PGP encrypted messages
       ~h EXPR      messages which contain EXPR in the message header
       ~k           message contains PGP key material
       ~i EXPR      message which match EXPR in the "Message-ID" field
       ~L EXPR      message is either originated or received by EXPR
       ~l           message is addressed to a known mailing list
       ~m MIN-MAX   message in the range MIN to MAX
       ~n MIN-MAX   messages with a score in the range MIN to MAX
       ~N           new messages
       ~O           old messages
       ~p           message is addressed to you (consults $alternates)
       ~P           message is from you (consults $alternates)
       ~Q           messages which have been replied to
       ~R           read messages
       ~r MIN-MAX   messages with "date-received" in a Date range
       ~S           superseded messages
       ~s EXPR      messages having EXPR in the "Subject" field.
       ~T           tagged messages
       ~t EXPR      messages addressed to EXPR
       ~U           unread messages
       ~v           message is part of a collapsed thread.
       ~x EXPR      messages which contain EXPR in the "References" field
       ~z MIN-MAX   messages with a size in the range MIN to MAX
       ~=           duplicated messages (see $duplicate_threads)

       In the above, EXPR is a regular expression.

       With  the  ~m, ~n, and ~z operators, you can also specify ranges in the
       forms <MAX, >MIN, MIN-, and -MAX.

   Matching dates
       The ~d and ~r operators are used to match date ranges, which are inter-
       preted to be given in your local time zone.

       A  date  is  of  the  form DD[/MM[/[cc]YY]], that is, a two-digit date,
       optionally followed by a two-digit month, optionally followed by a year
       specifications.   Omitted fields default to the current month and year.

       Mutt understands either two or four digit  year  specifications.   When
       given  a  two-digit  year,  mutt  will interpret values less than 70 as
       lying in the 21st century (i.e., "38" means 2038 and not 1938, and "00"
       is  interpreted  as  2000),  and  values greater than or equal to 70 as
       lying in the 20th century.

       Note that this behaviour is Y2K compliant, but that mutt  does  have  a
       Y2.07K problem.

       If  a  date  range  consists of a single date, the operator in question
       will match that precise date.  If the date range  consists  of  a  dash
       ("-"), followed by a date, this range will match any date before and up
       to the date given.  Similarly, a date followed by a  dash  matches  the
       date  given  and  any  later  point of time.  Two dates, separated by a
       dash, match any date which lies in the given range of time.

       You can also modify any absolute date by giving  an  error  range.   An
       error  range  consists  of one of the characters +, -, *, followed by a
       positive number, followed by one of the unit characters y, m, w, or  d,
       specifying  a  unit  of years, months, weeks, or days.  + increases the
       maximum date matched by the given interval of  time,  -  decreases  the
       minimum date matched by the given interval of time, and * increases the
       maximum date and decreases the minimum date matched by the given inter-
       val  of  time.   It  is  possible to give multiple error margins, which
       cumulate.  Example: 1/1/2001-1w+2w*3d

       You can also specify offsets relative to the current date.   An  offset
       is  specified  as one of the characters <, >, =, followed by a positive
       number, followed by one of the unit  characters  y,  m,  w,  or  d.   >
       matches  dates  which  are  older than the specified amount of time, an
       offset which begins with the character < matches dates which  are  more
       recent  than  the  specified amount of time, and an offset which begins
       with the character = matches points of time  which  are  precisely  the
       given amount of time ago.

CONFIGURATION VARIABLES
       abort_nosubject
              Type: quadoption
              Default: ask-yes

              If  set  to yes, when composing messages and no subject is given
              at the subject prompt, composition will be aborted.  If  set  to
              no,  composing  messages  with  no  subject given at the subject
              prompt will never be aborted.



       abort_unmodified
              Type: quadoption
              Default: yes

              If set to yes, composition will automatically abort after  edit-
              ing  the  message  body if no changes are made to the file (this
              check only happens after the first edit of the file).  When  set
              to no, composition will never be aborted.



       alias_file
              Type: path
              Default: "~/.muttrc"

              The  default  file in which to save aliases created by the "cre-
              ate-alias" function.

              Note: Mutt will not automatically source  this  file;  you  must
              explicitly use the "source" command for it to be executed.



       alias_format
              Type: string
              Default: "%4n %2f %t %-10a   %r"

              Specifies the format of the data displayed for the `alias' menu.
              The following printf(3)-style sequences are available:



              %a     alias name


              %f     flags - currently, a "d" for an alias marked for deletion


              %n     index number


              %r     address which alias expands to


              %t     character  which  indicates  if  the  alias is tagged for
                     inclusion



       allow_8bit
              Type: boolean
              Default: yes

              Controls whether 8-bit data is converted to 7-bit  using  either
              Quoted- Printable or Base64 encoding when sending mail.



       allow_ansi
              Type: boolean
              Default: no

              Controls whether ANSI color codes in messages (and color tags in
              rich text messages) are to be interpreted.  Messages  containing
              these codes are rare, but if this option is set, their text will
              be colored accordingly. Note that this may override  your  color
              choices,  and  even  present a security problem, since a message
              could include a line like "[-- PGP output follows ..." and  give
              it the same color as your attachment color.



       alternates
              Type: regular expression
              Default: ""

              A  regexp  that  allows you to specify alternate addresses where
              you receive mail.  This affects Mutt's idea about messages  from
              you and addressed to you.



       arrow_cursor
              Type: boolean
              Default: no

              When  set,  an arrow ("->") will be used to indicate the current
              entry in menus instead of hiliting the whole line.  On slow net-
              work or modem links this will make response faster because there
              is less that has to be redrawn on the screen when moving to  the
              next or previous entries in the menu.



       ascii_chars
              Type: boolean
              Default: no

              If  set,  Mutt  will  use plain ASCII characters when displaying
              thread and attachment trees, instead of the default ACS  charac-
              ters.



       askbcc
              Type: boolean
              Default: no

              If set, Mutt will prompt you for blind-carbon-copy (Bcc) recipi-
              ents before editing an outgoing message.



       askcc
              Type: boolean
              Default: no

              If set, Mutt will prompt you  for  carbon-copy  (Cc)  recipients
              before editing the body of an outgoing message.



       attach_format
              Type: string
              Default: "%u%D%I %t%4n %T%.40d%> [%.7m/%.10M, %.6e%?C?, %C?, %s] "

              This  variable  describes  the  format of the `attachment' menu.
              The following printf-style sequences are understood:



              %D     deleted flag


              %d     description


              %e     MIME content-transfer-encoding


              %f     filename


              %I     disposition (I=inline, A=attachment)


              %m     major MIME type


              %M     MIME subtype


              %n     attachment number


              %s     size


              %t     tagged flag


              %u     unlink (=to delete) flag


              %>X    right justify the rest of the string and pad with charac-
                     ter "X"


              %|X    pad to the end of the line with character "X"



       attach_sep
              Type: string
              Default: "\n"

              The separator to add between attachments when operating (saving,
              printing, piping, etc) on a list of tagged attachments.



       attach_split
              Type: boolean
              Default: yes

              If this variable is unset,  when  operating  (saving,  printing,
              piping, etc) on a list of tagged attachments, Mutt will concate-
              nate the attachments and  will  operate  on  them  as  a  single
              attachment.  The  "$attach_sep"  separator  is  added after each
              attachment. When set, Mutt will operate on the  attachments  one
              by one.



       attribution
              Type: string
              Default: "On %d, %n wrote:"

              This  is  the  string that will precede a message which has been
              included  in  a  reply.   For  a   full   listing   of   defined
              printf()-like sequences see the section on "$index_format".



       autoedit
              Type: boolean
              Default: no

              When  set along with "$edit_headers", Mutt will skip the initial
              send-menu and allow you to immediately begin editing the body of
              your message.  The send-menu may still be accessed once you have
              finished editing the body of your message.

              Also see "$fast_reply".



       auto_tag
              Type: boolean
              Default: no

              When set, functions in the index menu  which  affect  a  message
              will be applied to all tagged messages (if there are any).  When
              unset, you must first use the tag-prefix function (default: ";")
              to make the next function apply to all tagged messages.



       beep
              Type: boolean
              Default: yes

              When  this variable is set, mutt will beep when an error occurs.



       beep_new
              Type: boolean
              Default: no

              When this variable is set, mutt will beep whenever it  prints  a
              message  notifying  you of new mail.  This is independent of the
              setting of the "$beep" variable.



       bounce_delivered
              Type: boolean
              Default: yes

              When this variable is set, mutt will include Delivered-To  head-
              ers  when  bouncing  messages.   Postfix users may wish to unset
              this variable.



       charset
              Type: string
              Default: ""

              Character set your terminal uses to display  and  enter  textual
              data.



       check_new
              Type: boolean
              Default: yes

              Note: this option only affects maildir and MH style mailboxes.

              When set, Mutt will check for new mail delivered while the mail-
              box is open.  Especially with MH mailboxes, this  operation  can
              take  quite  some  time since it involves scanning the directory
              and checking each file to see if it has already been looked  at.
              If  check_new is unset, no check for new mail is performed while
              the mailbox is open.



       collapse_unread
              Type: boolean
              Default: yes

              When unset, Mutt will not collapse a thread if it  contains  any
              unread messages.



       uncollapse_jump
              Type: boolean
              Default: no

              When  set,  Mutt  will  jump to the next unread message, if any,
              when the current thread is uncollapsed.



       compose_format
              Type: string
              Default: "-- Mutt: Compose  [Approx. msg size: %l   Atts: %a]%>-"

              Controls the format of the status line displayed in  the  \fCom-
              pose  menu.  This string is similar to "$status_format", but has
              its own set of printf()-like sequences:



              %a     total number of attachments


              %h     local hostname


              %l     approximate size (in bytes) of the current message


              %v     Mutt version string


              See the text describing the  "$status_format"  option  for  more
              information on how to set "$compose_format".



       confirmappend
              Type: boolean
              Default: yes

              When  set, Mutt will prompt for confirmation when appending mes-
              sages to an existing mailbox.



       confirmcreate
              Type: boolean
              Default: yes

              When set, Mutt will prompt for confirmation when saving messages
              to a mailbox which does not yet exist before creating it.



       connect_timeout
              Type: number
              Default: 30

              Causes  Mutt  to  timeout a network connection (for IMAP or POP)
              after this many seconds if the connection  is  not  able  to  be
              established.   A negative value causes Mutt to wait indefinitely
              for the connection to succeed.



       copy
              Type: quadoption
              Default: yes

              This variable controls whether or not copies  of  your  outgoing
              messages   will   be  saved  for  later  references.   Also  see
              "$record", "$save_name", "$force_name" and "fcc-hook".



       date_format
              Type: string
              Default: "!%a, %b %d, %Y at %I:%M:%S%p %Z"

              This variable controls the format of the  date  printed  by  the
              "%d"  sequence  in "$index_format".  This is passed to the strf-
              time call to process the date. See the man page for  strftime(3)
              for the proper syntax.

              Unless  the  first  character in the string is a bang ("!"), the
              month and week day names are expanded according  to  the  locale
              specified  in  the variable "$locale". If the first character in
              the string is a bang, the bang is discarded, and the  month  and
              week  day  names in the rest of the string are expanded in the C
              locale (that is in US English).



       default_hook
              Type: string
              Default: "~f %s !~P | (~P ~C %s)"

              This variable  controls  how  send-hooks,  message-hooks,  save-
              hooks,  and  fcc-hooks will be interpreted if they are specified
              with only a simple regexp, instead of a matching  pattern.   The
              hooks  are  expanded  when  they are declared, so a hook will be
              interpreted according to the value of this variable at the  time
              the  hook is declared.  The default value matches if the message
              is either from a user matching the regular expression given,  or
              if  it  is  from you (if the from address matches "$alternates")
              and is to or cc'ed to a user matching the given regular  expres-
              sion.



       delete
              Type: quadoption
              Default: ask-yes

              Controls whether or not messages are really deleted when closing
              or synchronizing a mailbox.  If set to yes, messages marked  for
              deleting will automatically be purged without prompting.  If set
              to no, messages marked for deletion will be kept in the mailbox.



       delete_untag
              Type: boolean
              Default: yes

              If  this  option  is  set, mutt will untag messages when marking
              them for deletion.  This  applies  when  you  either  explicitly
              delete a message, or when you save it to another folder.



       digest_collapse
              Type: boolean
              Default: yes

              If  this  option is set, mutt's revattach menu will not show the
              subparts of individual messages in a digest.  To see these  sub-
              parts, press 'v' on that menu.



       display_filter
              Type: path
              Default: ""

              When  set,  specifies a command used to filter messages.  When a
              message is viewed it  is  passed  as  standard  input  to  $dis-
              play_filter,  and the filtered message is read from the standard
              output.



       dsn_notify
              Type: string
              Default: ""

              Note: you should not enable this unless you are  using  Sendmail
              8.8.x or greater.

              This   variable  sets  the  request  for  when  notification  is
              returned.  The string consists of a  comma  separated  list  (no
              spaces!)  of  one  or  more  of  the  following: never, to never
              request notification, failure, to request notification on trans-
              mission  failure,  delay, to be notified of message delays, suc-
              cess, to be notified of successful transmission.

              Example: set dsn_notify="failure,delay"



       dsn_return
              Type: string
              Default: ""

              Note: you should not enable this unless you are  using  Sendmail
              8.8.x or greater.

              This  variable  controls how much of your message is returned in
              DSN messages.  It may be set to either hdrs to return  just  the
              message header, or full to return the full message.

              Example: set dsn_return=hdrs



       duplicate_threads
              Type: boolean
              Default: yes

              This  variable  controls  whether mutt, when sorting by threads,
              threads messages with the same message-id together.   If  it  is
              set, it will indicate that it thinks they are duplicates of each
              other with an equals sign in the thread diagram.



       edit_headers
              Type: boolean
              Default: no

              This option allows you to edit the header of your outgoing  mes-
              sages along with the body of your message.



       editor
              Type: path
              Default: ""

              This  variable  specifies  which  editor  is  used  by mutt.  It
              defaults to the value of  the  VISUAL,  or  EDITOR,  environment
              variable, or to the string "vi" if neither of those are set.



       encode_from
              Type: boolean
              Default: no

              When  set,  mutt will quoted-printable encode messages when they
              contain the string "From " in the beginning of a  line.   Useful
              to  avoid  the  tampering  certain  mail  delivery and transport
              agents tend to do with messages.



       envelope_from
              Type: boolean
              Default: no

              When set, mutt will try to derive the message's envelope  sender
              from  the  "From:" header.  Note that this information is passed
              to sendmail command using the "-f" command line switch, so don't
              set  this option if you are using that switch in $sendmail your-
              self, or if the sendmail on your machine  doesn't  support  that
              command line switch.



       escape
              Type: string
              Default: "~"

              Escape character to use for functions in the builtin editor.



       fast_reply
              Type: boolean
              Default: no

              When  set,  the  initial  prompt  for recipients and subject are
              skipped when replying to messages, and the  initial  prompt  for
              subject is skipped when forwarding messages.

              Note:  this variable has no effect when the "$autoedit" variable
              is set.



       fcc_attach
              Type: boolean
              Default: yes

              This variable controls whether or not  attachments  on  outgoing
              messages are saved along with the main body of your message.



       fcc_clear
              Type: boolean
              Default: no

              When  this  variable is set, FCCs will be stored unencrypted and
              unsigned, even when  the  actual  message  is  encrypted  and/or
              signed.



       folder
              Type: path
              Default: "~/Mail"

              Specifies  the default location of your mailboxes.  A `+' or `='
              at the beginning of a pathname will be expanded to the value  of
              this  variable.   Note that if you change this variable from the
              default value you need to make sure that the  assignment  occurs
              before  you  use `+' or `=' for any other variables since expan-
              sion takes place during the `set' command.



       folder_format
              Type: string
              Default: "%2C %t %N %F %2l %-8.8u %-8.8g %8s %d %f"

              This variable allows you to customize the file  browser  display
              to  your personal taste.  This string is similar to "$index_for-
              mat", but has its own set of printf()-like sequences:



              %C     current file number


              %d     date/time folder was last modified


              %f     filename


              %F     file permissions


              %g     group name (or numeric gid, if missing)


              %l     number of hard links


              %N     N if folder has new mail, blank otherwise


              %s     size in bytes


              %t     * if the file is tagged, blank otherwise


              %u     owner name (or numeric uid, if missing)


              %>X    right justify the rest of the string and pad with charac-
                     ter "X"


              %|X    pad to the end of the line with character "X"



       followup_to
              Type: boolean
              Default: yes

              Controls  whether  or  not  the Mail-Followup-To header field is
              generated when sending mail.  When set, Mutt will generate  this
              field  when  you are replying to a known mailing list, specified
              with the "subscribe" or "lists" commands.

              This field has two purposes.  First, preventing you from receiv-
              ing  duplicate  copies  of replies to messages which you send to
              mailing lists.  Second, ensuring that you do get a  reply  sepa-
              rately for any messages sent to known lists to which you are not
              subscribed.  The header will contain only the list's address for
              subscribed  lists,  and both the list address and your own email
              address for unsubscribed lists.  Without this  header,  a  group
              reply  to your message sent to a subscribed list will be sent to
              both the list and your address, resulting in two copies  of  the
              same email for you.



       force_name
              Type: boolean
              Default: no

              This  variable is similar to "$save_name", except that Mutt will
              store a copy of your outgoing message by  the  username  of  the
              address  you are sending to even if that mailbox does not exist.

              Also see the "$record" variable.



       forward_decode
              Type: boolean
              Default: yes

              Controls the decoding of complex MIME messages  into  text/plain
              when  forwarding  a message.  The message header is also RFC2047
              decoded.  This variable is  only  used,  if  "$mime_forward"  is
              unset, otherwise "$mime_forward_decode" is used instead.



       forward_format
              Type: string
              Default: "[%a: %s]"

              This  variable  controls  the  default subject when forwarding a
              message.  It uses the same format sequences as the  "$index_for-
              mat" variable.



       forward_quote
              Type: boolean
              Default: no

              When  set  forwarded  messages  included in the main body of the
              message (when "$mime_forward" is unset)  will  be  quoted  using
              "$indent_string".



       from
              Type: e-mail address
              Default: ""

              When set, this variable contains a default from address.  It can
              be overridden  using  my_hdr  (including  from  send-hooks)  and
              "$reverse_name".

              Defaults to the EMAIL environment variable's content.



       gecos_mask
              Type: regular expression
              Default: "^[^,]*"

              A  regular expression used by mutt to parse the GECOS field of a
              password entry when expanding the alias.  By default the regular
              expression is set to "^[^,]*" which will return the string up to
              the first "," encountered.  If the GECOS field contains a string
              like   "lastname,   firstname"   then   you   should   set   the
              gecos_mask=".*".

              This can be useful  if  you  see  the  following  behavior:  you
              address  a  e-mail  to  user  ID stevef whose full name is Steve
              Franklin.  If mutt expands stevef to  "Franklin"  stevef@foo.bar
              then  you should set the gecos_mask to a regular expression that
              will match the whole name so  mutt  will  expand  "Franklin"  to
              "Franklin, Steve".



       hdrs
              Type: boolean
              Default: yes

              When  unset,  the  header  fields normally added by the "my_hdr"
              command are not created.  This variable  must  be  unset  before
              composing a new message or replying in order to take effect.  If
              set, the user defined header fields are added to every new  mes-
              sage.



       header
              Type: boolean
              Default: no

              When set, this variable causes Mutt to include the header of the
              message you are replying to into the edit buffer.   The  "$weed"
              setting applies.



       help
              Type: boolean
              Default: yes

              When set, help lines describing the bindings for the major func-
              tions provided by each menu are displayed on the first  line  of
              the screen.

              Note:  The  binding will not be displayed correctly if the func-
              tion is bound to a sequence  rather  than  a  single  keystroke.
              Also,  the  help line may not be updated if a binding is changed
              while Mutt is running.  Since this variable is  primarily  aimed
              at new users, neither of these should present a major problem.



       hidden_host
              Type: boolean
              Default: no

              When set, mutt will skip the host name part of "$hostname" vari-
              able when adding the domain part to  addresses.   This  variable
              does  not  affect the generation of Message-IDs, and it will not
              lead to the cut-off of first-level domains.



       hide_limited
              Type: boolean
              Default: no

              When set, mutt will not show the presence of missing messages in
              the thread tree.



       hide_missing
              Type: boolean
              Default: yes

              When  set,  mutt will not show the presence of messages that are
              hidden by limiting, in the thread tree.



       hide_top_limited
              Type: boolean
              Default: no

              When set, mutt will not show the presence of missing messages at
              the  top  of  threads  in  the  thread  tree.   Note  that  when
              $hide_limited is set, this option will have no effect.



       hide_top_missing
              Type: boolean
              Default: yes

              When set, mutt will not show the presence of messages  that  are
              hidden  by  limiting,  at  the  top  of  threads  in  the thread
              tree.Note that when $hide_missing is set, this option will  have
              no effect.



       history
              Type: number
              Default: 10

              This  variable  controls  the  size (in number of strings remem-
              bered) of the string history buffer. The buffer is cleared  each
              time the variable is set.



       honor_followup_to
              Type: quadoption
              Default: yes

              This  variable controls whether or not a Mail-Followup-To header
              is honored when group-replying to a message.



       hostname
              Type: string
              Default: ""

              Specifies the hostname to use after  the  "@"  in  local  e-mail
              addresses.   This overrides the compile time definition obtained
              from /etc/resolv.conf.



       ignore_list_reply_to
              Type: boolean
              Default: no

              Affects the behaviour of the reply  function  when  replying  to
              messages from mailing lists.  When set, if the "Reply-To:" field
              is set to the same value as the "To:" field, Mutt  assumes  that
              the  "Reply-To:"  field  was set by the mailing list to automate
              responses to the list, and will ignore this field.  To direct  a
              response  to  the  mailing list when this option is set, use the
              list-reply function; group-reply will reply to both  the  sender
              and the list.



       imap_authenticators
              Type: string
              Default: ""

              This  is  a  colon-delimited list of authentication methods mutt
              may attempt to use to log in to an IMAP  server,  in  the  order
              mutt should try them.  Authentication methods are either 'login'
              or the right side of an IMAP 'AUTH=xxx'  capability  string,  eg
              'digest-md5', parameter is unset (the default) mutt will try all
              available methods, in order from most-secure to least-secure.

              Example: set imap_authenticators="gssapi:cram-md5:login"

              Note: Mutt will only fall back to other  authentication  methods
              if  the  previous methods are unavailable. If a method is avail-
              able but authentication fails, mutt will not connect to the IMAP
              server.



       imap_delim_chars
              Type: string
              Default: "/."

              This  contains  the  list  of characters which you would like to
              treat as folder separators for displaying IMAP paths. In partic-
              ular  it  helps  in using the '=' shortcut for your folder vari-
              able.



       imap_force_ssl
              Type: boolean
              Default: no

              If this variable is set, Mutt will always use SSL when  connect-
              ing to IMAP servers.



       imap_home_namespace
              Type: string
              Default: ""

              You  normally  want  to see your personal folders alongside your
              INBOX in the IMAP browser. If you see something  else,  you  may
              set this variable to the IMAP path to your folders.



       imap_keepalive
              Type: number
              Default: 900

              This  variable  specifies  the maximum amount of time in seconds
              that mutt will wait before polling  open  IMAP  connections,  to
              prevent  the  server  from closing them before mutt has finished
              with them. The default is well within the RFC-specified  minimum
              amount  of  time  (30  minutes) before a server is allowed to do
              this, but in practice the RFC does get violated  every  now  and
              then.  Reduce  this  number if you find yourself getting discon-
              nected from your IMAP server due to inactivity.



       imap_list_subscribed
              Type: boolean
              Default: no

              This variable configures whether IMAP folder browsing will  look
              for only subscribed folders or all folders.  This can be toggled
              in the IMAP browser with the toggle-subscribed function.



       imap_pass
              Type: string
              Default: ""

              Specifies the password for your IMAP account.   If  unset,  Mutt
              will prompt you for your password when you invoke the fetch-mail
              function.  Warning: you should only use this option when you are
              on  a fairly secure machine, because the superuser can read your
              muttrc even if you are the only one who can read the file.



       imap_passive
              Type: boolean
              Default: yes

              When set, mutt will not open new IMAP connections to  check  for
              new  mail.  Mutt will only check for new mail over existing IMAP
              connections.  This is useful if you don't want to be prompted to
              user/password  pairs  on mutt invocation, or if opening the con-
              nection is slow.



       imap_peek
              Type: boolean
              Default: yes

              If set, mutt will avoid implicitly marking  your  mail  as  read
              whenever  you fetch a message from the server. This is generally
              a good thing, but can  make  closing  an  IMAP  folder  somewhat
              slower. This option exists to appease speed freaks.



       imap_servernoise
              Type: boolean
              Default: yes

              When  set,  mutt  will  display  warning  messages from the IMAP
              server as error messages. Since these messages are  often  harm-
              less,  or  generated due to configuration problems on the server
              which are out of the users' hands, you may wish to suppress them
              at some point.



       imap_user
              Type: string
              Default: ""

              Your login name on the IMAP server.

              This variable defaults to your user name on the local machine.



       implicit_autoview
              Type: boolean
              Default: no

              If  set  to  "yes",  mutt will look for a mailcap entry with the
              copiousoutput flag set for every MIME attachment it doesn't have
              an internal viewer defined for.  If such an entry is found, mutt
              will use the viewer defined in that entry to  convert  the  body
              part to text form.



       include
              Type: quadoption
              Default: ask-yes

              Controls  whether or not a copy of the message(s) you are reply-
              ing to is included in your reply.



       indent_string
              Type: string
              Default: "> "

              Specifies the string to prepend to each line of text quoted in a
              message  to which you are replying.  You are strongly encouraged
              not to change this value, as it tends to agitate the more fanat-
              ical netizens.



       index_format
              Type: string
              Default: "%4C %Z %{%b %d} %-15.15L (%4l) %s"

              This  variable allows you to customize the message index display
              to your personal taste.

              "Format strings" are similar to the  strings  used  in  the  "C"
              function  printf  to  format  output  (see the man page for more
              detail).  The following sequences are defined in Mutt:



              %a     address of the author


              %b     filename of the original message folder (think mailBox)


              %B     the list to which the letter was sent, or else the folder
                     name (%b).


              %c     number of characters (bytes) in the message


              %C     current message number


              %d     date  and  time of the message in the format specified by
                     "date_format" converted to sender's time zone


              %D     date and time of the message in the format  specified  by
                     "date_format" converted to the local time zone


              %e     current message number in thread


              %E     number of messages in current thread


              %f     entire From: line (address + real name)


              %F     author name, or recipient name if the message is from you


              %i     message-id of the current message


              %l     number of lines in the message


              %L     If an address in the To or CC  header  field  matches  an
                     address  defined  by the users "lists" command, this dis-
                     plays "To <list-name>", otherwise the same as %F.


              %m     total number of message in the mailbox


              %M     number of hidden messages if the thread is collapsed.


              %N     message score


              %n     author's real name (or address if missing)


              %O     (_O_riginal save folder)  Where mutt would formerly  have
                     stashed  the  message:  list name or recipient name if no
                     list


              %s     subject of the message


              %S     status of the message (N/D/d/!/r/*)


              %t     `to:' field (recipients)


              %T     the appropriate character from the $to_chars string


              %u     user (login) name of the author


              %v     first name of the author, or the recipient if the message
                     is from you


              %y     `x-label:' field, if present


              %Y     `x-label'  field,  if  present,  and (1) not at part of a
                     thread tree, (2) at the top of a thread, or (3) `x-label'
                     is different from preceding message's `x-label'.


              %Z     message status flags


              %{fmt} the date and time of the message is converted to sender's
                     time zone, and "fmt" is expanded by the library  function
                     "strftime"; a leading bang disables locales


              %[fmt] the  date  and  time  of  the message is converted to the
                     local time zone, and "fmt" is  expanded  by  the  library
                     function "strftime"; a leading bang disables locales


              %(fmt) the  local  date  and time when the message was received.
                     "fmt" is expanded by the library function  "strftime";  a
                     leading bang disables locales


              %<fmt> the  current local time. "fmt" is expanded by the library
                     function "strftime"; a leading bang disables locales.


              %>X    right justify the rest of the string and pad with charac-
                     ter "X"


              %|X    pad to the end of the line with character "X"


              See also: "$to_chars".



       ispell
              Type: path
              Default: "/usr/bin/ispell"

              How to invoke ispell (GNU's spell-checking software).



       keep_flagged
              Type: boolean
              Default: no

              If  set,  read messages marked as flagged will not be moved from
              your spool mailbox to your "$mbox" mailbox, or as a result of  a
              "mbox-hook" command.



       locale
              Type: string
              Default: "C"

              The locale used by strftime(3) to format dates. Legal values are
              the strings your system accepts for the locale variable LC_TIME.



       mail_check
              Type: number
              Default: 5

              This variable configures how often (in seconds) mutt should look
              for new mail.



       mailcap_path
              Type: string
              Default: ""

              This variable specifies which files to consult  when  attempting
              to display MIME bodies not directly supported by Mutt.



       mailcap_sanitize
              Type: boolean
              Default: yes

              If  set,  mutt  will  restrict  possible characters in mailcap %
              expandos to a well-defined set of safe characters.  This is  the
              safe  setting,  but  we  are not sure it doesn't break some more
              advanced MIME stuff.

              DON'T CHANGE THIS SETTING UNLESS YOU ARE REALLY  SURE  WHAT  YOU
              ARE DOING!



       maildir_trash
              Type: boolean
              Default: no

              If  set,  messages  marked  as  deleted  will  be saved with the
              maildir (T)rashed flag instead of  unlinked.   NOTE:  this  only
              applies  to  maildir-style  mailboxes.   Setting it will have no
              effect on other mailbox types.



       mark_old
              Type: boolean
              Default: yes

              Controls whether or not Mutt makes the distinction  between  new
              messages  and  old  unread messages.  By default, Mutt will mark
              new messages as old if you exit a mailbox without reading  them.
              The  next time you start Mutt, the messages will show up with an
              "O" next to them in the index menu,  indicating  that  they  are
              old.   In  order  to  make Mutt treat all unread messages as new
              only, you can unset this variable.



       markers
              Type: boolean
              Default: yes

              Controls the display of wrapped lines in the internal pager.  If
              set,  a  "+"  marker  is  displayed  at the beginning of wrapped
              lines. Also see the "$smart_wrap" variable.



       mask
              Type: regular expression
              Default: "!^\.[^.]"

              A regular expression used in the file browser,  optionally  pre-
              ceded  by  the  not  operator "!".  Only files whose names match
              this mask will be shown. The match is always case-sensitive.



       mbox
              Type: path
              Default: "~/mbox"

              This  specifies  the  folder  into  which  read  mail  in   your
              "$spoolfile" folder will be appended.



       mbox_type
              Type: folder magic
              Default: mbox

              The  default mailbox type used when creating new folders. May be
              any of mbox, MMDF, MH and Maildir.



       metoo
              Type: boolean
              Default: no

              If unset, Mutt will remove your address (see  the  "$alternates"
              variable)  from  the  list of recipients when replying to a mes-
              sage.



       menu_scroll
              Type: boolean
              Default: no

              When set, menus will be scrolled up or down one  line  when  you
              attempt  to move across a screen boundary.  If unset, the screen
              is cleared and the next or previous page of  the  menu  is  dis-
              played (useful for slow links to avoid many redraws).



       meta_key
              Type: boolean
              Default: no

              If  set,  forces  Mutt to interpret keystrokes with the high bit
              (bit 8) set as if the user had pressed the ESC key and  whatever
              key  remains after having the high bit removed.  For example, if
              the key pressed has an ASCII value of 0xf4, then this is treated
              as  if  the  user had pressed ESC then "x".  This is because the
              result of removing the high bit from "0xf4" is "0x74", which  is
              the ASCII character "x".



       mh_purge
              Type: boolean
              Default: no

              When  unset,  mutt  will mimic mh's behaviour and rename deleted
              messages to ,<old file name> in mh  folders  instead  of  really
              deleting  them.   If the variable is set, the message files will
              simply be deleted.



       mh_seq_flagged
              Type: string
              Default: "flagged"

              The name of the MH sequence used for flagged messages.



       mh_seq_replied
              Type: string
              Default: "replied"

              The name of the MH sequence used to tag replied messages.



       mh_seq_unseen
              Type: string
              Default: "unseen"

              The name of the MH sequence used for unseen messages.



       mime_forward
              Type: quadoption
              Default: no

              When set, the message you are forwarding will be attached  as  a
              separate  MIME  part instead of included in the main body of the
              message.  This is useful for forwarding  MIME  messages  so  the
              receiver  can  properly  view the message as it was delivered to
              you. If you like to switch between MIME and not MIME  from  mail
              to mail, set this variable to ask-no or ask-yes.

              Also see "$forward_decode" and "$mime_forward_decode".



       mime_forward_decode
              Type: boolean
              Default: no

              Controls  the  decoding of complex MIME messages into text/plain
              when forwarding a message while "$mime_forward" is  set.  Other-
              wise "$forward_decode" is used instead.



       mime_forward_rest
              Type: quadoption
              Default: yes

              When  forwarding multiple attachments of a MIME message from the
              recvattach menu, attachments which cannot be decoded in  a  rea-
              sonable manner will be attached to the newly composed message if
              this option is set.



       mix_entry_format
              Type: string
              Default: "%4n %c %-16s %a"

              This variable describes the format of a  remailer  line  on  the
              mixmaster  chain  selection  screen.   The following printf-like
              sequences are supported:



              %n     The running number on the menu.


              %c     Remailer capabilities.


              %s     The remailer's short name.


              %a     The remailer's e-mail address.



       mixmaster
              Type: path
              Default: "mixmaster"

              This variable contains the path to the Mixmaster binary on  your
              system.   It  is  used with various sets of parameters to gather
              the list of known remailers,  and  to  finally  send  a  message
              through the mixmaster chain.



       move
              Type: quadoption
              Default: ask-no

              Controls  whether  you will be asked to confirm moving read mes-
              sages from your spool mailbox to your "$mbox" mailbox, or  as  a
              result of a "mbox-hook" command.



       message_format
              Type: string
              Default: "%s"

              This  is  the  string  displayed  in  the  "attachment" menu for
              attachments of type  message/rfc822.   For  a  full  listing  of
              defined  printf()-like sequences see the section on "$index_for-
              mat".



       pager
              Type: path
              Default: "builtin"

              This variable specifies which pager you would  like  to  use  to
              view  messages.   builtin means to use the builtin pager, other-
              wise this variable should specify the pathname of  the  external
              pager you would like to use.

              Using  an external pager may have some disadvantages: Additional
              keystrokes are necessary because you can't call  mutt  functions
              directly  from  the pager, and screen resizes cause lines longer
              than the screen width to be badly formatted in the help menu.



       pager_context
              Type: number
              Default: 0

              This variable controls the number of lines of context  that  are
              given  when displaying the next or previous page in the internal
              pager.  By default, Mutt will display the line  after  the  last
              one  on  the screen at the top of the next page (0 lines of con-
              text).



       pager_format
              Type: string
              Default: "-%Z- %C/%m: %-20.20n   %s"

              This variable controls the format of the one-line message  "sta-
              tus"  displayed before each message in either the internal or an
              external  pager.   The  valid  sequences  are  listed   in   the
              "$index_format" section.



       pager_index_lines
              Type: number
              Default: 0

              Determines  the  number  of lines of a mini-index which is shown
              when in the pager.  The current message, unless near the top  or
              bottom  of the folder, will be roughly one third of the way down
              this mini-index, giving the reader the context of a few messages
              before  and  after the message.  This is useful, for example, to
              determine how many messages remain to be  read  in  the  current
              thread.   One  of  the lines is reserved for the status bar from
              the index, so a pager_index_lines of 6 will only show 5 lines of
              the actual index.  A value of 0 results in no index being shown.
              If the number of messages in the current  folder  is  less  than
              pager_index_lines, then the index will only use as many lines as
              it needs.



       pager_stop
              Type: boolean
              Default: no

              When set, the internal-pager will not move to the  next  message
              when  you  are  at the end of a message and invoke the next-page
              function.



       pgp_autosign
              Type: boolean
              Default: no

              Setting this variable will  cause  Mutt  to  always  attempt  to
              PGP/MIME  sign outgoing messages.  This can be overridden by use
              of the pgp- menu, when signing is not required or encryption  is
              requested as well.



       pgp_autoencrypt
              Type: boolean
              Default: no

              Setting  this  variable  will  cause  Mutt  to always attempt to
              PGP/MIME encrypt outgoing messages.  This is probably only  use-
              ful  in connection to the send-hook command.  It can be overrid-
              den by use of the pgp-menu, when encryption is not  required  or
              signing is requested as well.



       pgp_ignore_subkeys
              Type: boolean
              Default: yes

              Setting this variable will cause Mutt to ignore OpenPGP subkeys.
              Instead, the principal key will inherit the  subkeys'  capabili-
              ties.   Unset this if you want to play interesting key selection
              games.



       pgp_entry_format
              Type: string
              Default: "%4n %t%f %4l/0x%k %-4a %2c %u"

              This variable allows you to customize the PGP key selection menu
              to  your  personal taste. This string is similar to "$index_for-
              mat", but has its own set of printf()-like sequences:



              %n     number


              %k     key id


              %u     user id


              %a     algorithm


              %l     key length


              %f     flags


              %c     capabilities


              %t     trust/validity of the key-uid association


              %[<s>] date of the key where <s> is an strftime(3) expression



       pgp_good_sign
              Type: regular expression
              Default: ""

              If you assign a text to this variable, then a PGP  signature  is
              only  considered verified if the output from $pgp_verify_command
              contains the text. Use this variable if the exit code  from  the
              command is 0 even for bad signatures.



       pgp_long_ids
              Type: boolean
              Default: no

              If set, use 64 bit PGP key IDs. Unset uses the normal 32 bit Key
              IDs.



       pgp_replyencrypt
              Type: boolean
              Default: yes

              If set, automatically PGP encrypt replies to messages which  are
              encrypted.



       pgp_replysign
              Type: boolean
              Default: no

              If  set,  automatically  PGP  sign replies to messages which are
              signed.

              Note: this does not work on  messages  that  are  encrypted  and
              signed!



       pgp_replysignencrypted
              Type: boolean
              Default: no

              If  set,  automatically  PGP  sign replies to messages which are
              encrypted. This makes sense in combination  with  "$pgp_replyen-
              crypt",  because  it  allows  you to sign all messages which are
              automatically encrypted.  This works around the problem noted in
              "$pgp_replysign",  that  mutt is not able to find out whether an
              encrypted message is also signed.



       pgp_retainable_sigs
              Type: boolean
              Default: no

              If set, signed and encrypted messages  will  consist  of  nested
              multipart/signed and multipart/encrypted body parts.

              This  is useful for applications like encrypted and signed mail-
              ing lists, where the outer layer  (multipart/encrypted)  can  be
              easily   removed,  while  the  inner  multipart/signed  part  is
              retained.



       pgp_show_unusable
              Type: boolean
              Default: yes

              If set, mutt will display non-usable keys on the PGP key  selec-
              tion  menu.   This  includes  keys which have been revoked, have
              expired, or have been marked as "disabled" by the user.



       pgp_sign_as
              Type: string
              Default: ""

              If you have more than one key pair, this option  allows  you  to
              specify  which  of  your private keys to use.  It is recommended
              that  you  use  the  keyid  form  to  specify  your  key  (e.g.,
              "0x00112233").



       pgp_strict_enc
              Type: boolean
              Default: yes

              If  set, Mutt will automatically encode PGP/MIME signed messages
              as quoted-printable.  Please note that unsetting  this  variable
              may lead to problems with non-verifyable PGP signatures, so only
              change this if you know what you are doing.



       pgp_timeout
              Type: number
              Default: 300

              The number of seconds  after  which  a  cached  passphrase  will
              expire if not used.



       pgp_verify_sig
              Type: quadoption
              Default: yes

              If  "yes",  always  attempt  to  verify PGP/MIME signatures.  If
              "ask-yes" or "ask-no", ask whether or not to verify  the  signa-
              ture.  If "no", never attempt to verify PGP/MIME signatures.



       pgp_sort_keys
              Type: sort order
              Default: address

              Specifies how the entries in the `pgp keys' menu are sorted. The
              following are legal values:



              address
                     sort alphabetically by user id


              keyid  sort alphabetically by key id


              date   sort by key creation date


              trust  sort by the trust of the key


              If you prefer reverse order of the above values, prefix it  with
              `reverse-'.



       pgp_create_traditional
              Type: quadoption
              Default: no

              This  option  controls  whether  Mutt  generates  old-style  PGP
              encrypted or signed messages under certain circumstances.

              Note that PGP/MIME will be used automatically for messages which
              have  a  character set different from us-ascii, or which consist
              of more than a single MIME part.

              Also note  that  using  the  old-style  PGP  message  format  is
              strongly deprecated.



       pgp_decode_command
              Type: string
              Default: ""

              This  format strings specifies a command which is used to decode
              application/pgp attachments.

              The PGP command  formats  have  their  own  set  of  printf-like
              sequences:



              %p     Expands  to  PGPPASSFD=0 when a pass phrase is needed, to
                     an empty string otherwise. Note: This may be used with  a
                     %? construct.


              %f     Expands to the name of a file containing a message.


              %s     Expands  to  the  name of a file containing the signature
                     part
                                of a multipart/signed attachment when  verify-
                     ing it.


              %a     The value of $pgp_sign_as.


              %r     One or more key IDs.


              For  examples  on how to configure these formats for the various
              versions of PGP which are floating around, see the  pgp*.rc  and
              gpg.rc  files  in  the  samples/  subdirectory  which  has  been
              installed on your system alongside the documentation.



       pgp_getkeys_command
              Type: string
              Default: ""

              This command is invoked  whenever  mutt  will  need  public  key
              information.  %r is the only printf-like sequence used with this
              format.

       pgp_clearsign_command
              Type: string
              Default: ""

              This format is used to  create  a  "clearsigned"  old-style  PGP
              attachment.  Note that the use of this format is strongly depre-
              cated.



       pgp_sign_command
              Type: string
              Default: ""

              Type: string
              Default: ""

              This command is used to combinedly sign/encrypt a body part.



       pgp_encrypt_only_command
              Type: string
              Default: ""

              This  command is used to encrypt a body part without signing it.



       pgp_import_command
              Type: string
              Default: ""

              This command is used to import a key from  a  message  into  the

              ring.



       pgp_verify_key_command
              Type: string
              Default: ""

              This command is used to verify  key  information  from  the  key
              selection menu.



       pgp_list_secring_command
              Type: string
              Default: ""

              This  command  is  used  to list the secret key ring's contents.
              The output format must be analogous  to  the  one  used  by  gpg
              --list-keys --with-colons.

              This format is also generated by the pgpring utility which comes
              with mutt.



       pgp_list_pubring_command
              Type: string
              Default: ""

              This command is used to list the  public  key  ring's  contents.
              The  output  format  must  be  analogous  to the one used by gpg
              --list-keys --with-colons.

              This format is also generated by the pgpring utility which comes
              with mutt.



       forward_decrypt
              Type: boolean
              Default: yes

              Controls  the  handling  of encrypted messages when forwarding a
              message.  When set, the outer layer of  encryption  is  stripped
              off.   This  variable is only used if "$mime_forward" is set and
              "$mime_forward_decode" is unset.



       ssl_starttls
              Type: quadoption
              Default: yes

              If set (the default), mutt  will  attempt  to  use  STARTTLS  on
              servers  advertising  the  capability. When unset, mutt will not
              attempt to use STARTTLS regardless of the server's capabilities.



       certificate_file
              Type: path
              Default: ""

              This  variable  specifies  the  file  where the certificates you
              trust are saved. When an unknown certificate is encountered, you
              are  asked  if  you accept it or not. If you accept it, the cer-
              tificate can also be saved in this file and further  connections
              are automatically accepted.

              You  can  also  manually  add  CA certificates in this file. Any
              server certificate that is signed with one of these CA  certifi-
              cates are also automatically accepted.

              Example: set certificate_file=~/.mutt/certificates



       ssl_usesystemcerts
              Type: boolean
              Default: yes

              If  set to yes, mutt will use CA certificates in the system-wide
              certificate store when checking if server certificate is  signed
              by a trusted CA.



       entropy_file
              Type: path
              Default: ""

              The  file  which  includes random data that is used to initalize
              SSL library functions.



       ssl_use_sslv2
              Type: boolean
              Default: yes

              This variables specifies whether to attempt to use SSLv2 in  the
              SSL authentication process.



       ssl_use_sslv3
              Type: boolean
              Default: yes

              This  variables specifies whether to attempt to use SSLv3 in the
              SSL authentication process.



       ssl_use_tlsv1
              Type: boolean
              Default: yes

              This variables specifies whether to attempt to use TLSv1 in  the
              SSL authentication process.



       pipe_split
              Type: boolean
              Default: no

              Used  in  connection with the pipe-message command and the "tag-
              prefix" operator.  If this variable is unset, when piping a list
              of  tagged  messages Mutt will concatenate the messages and will
              pipe them as a single folder.  When set, Mutt will pipe the mes-
              sages  one  by one.  In both cases the messages are piped in the
              current sorted order, and the  "$pipe_sep"  separator  is  added
              after each message.



       pipe_decode
              Type: boolean
              Default: no

              Used  in  connection with the pipe-message command.  When unset,
              Mutt will pipe the messages without any preprocessing. When set,
              Mutt  will  weed headers and will attempt to PGP/MIME decode the
              messages first.



       pipe_sep
              Type: string
              Default: "\n"

              The separator to add between messages  when  piping  a  list  of
              tagged messages to an external Unix command.



       pop_authenticators
              Type: string
              Default: ""

              This  is  a  colon-delimited list of authentication methods mutt
              may attempt to use to log in to an POP server, in the order mutt
              should  try  them.   Authentication  methods  are either 'user',
              'apop' or any  SASL  mechanism,  eg  'digest-md5',  'gssapi'  or
              'cram-md5'.  This parameter is case-insensitive. If this parame-
              ter is unset (the default) mutt will try all available  methods,
              in order from most-secure to least-secure.

              Example: set pop_authenticators="digest-md5:apop:user"



       pop_auth_try_all
              Type: boolean
              Default: yes

              If  set,  Mutt  will try all available methods. When unset, Mutt
              will only fall back to other authentication methods if the  pre-
              vious  methods  are  unavailable.  If  a method is available but
              authentication fails, Mutt will not connect to the POP server.



       pop_checkinterval
              Type: number
              Default: 60

              This variable configures how often (in seconds) POP should  look
              for new mail.



       pop_delete
              Type: quadoption
              Default: ask-no

              If  set,  Mutt will delete successfully downloaded messages from
              the POP server when using the fetch-mail function.  When  unset,
              Mutt  will  download  messages  but  also  leave them on the POP
              server.



       pop_host
              Type: string
              Default: ""

              The name of your POP server for the  fetch-mail  function.   You
              can also specify an alternative port, username and password, ie:

              [pop[s]://][username[:password]@]popserver[:port]



       pop_last
              Type: boolean
              Default: no

              If this variable is set, mutt will try to  use  the  "LAST"  POP
              command  for retrieving only unread messages from the POP server
              when using the fetch-mail function.



       pop_reconnect
              Type: quadoption
              Default: ask-yes

              Controls whether or not Mutt will try to reconnect to POP server
              when connection lost.



       pop_user
              Type: string
              Default: ""

              Your login name on the POP server.

              This variable defaults to your user name on the local machine.



       pop_pass
              Type: string
              Default: ""

              Specifies  the  password  for  your POP account.  If unset, Mutt
              will prompt you for your password when  you  open  POP  mailbox.
              Warning:  you  should  only  use  this  option when you are on a
              fairly secure machine, because the superuser can read your  mut-
              trc even if you are the only one who can read the file.



       post_indent_string
              Type: string
              Default: ""

              Similar  to  the  "$attribution" variable, Mutt will append this
              string after the inclusion of a message which is  being  replied
              to.



       postpone
              Type: quadoption
              Default: ask-yes

              Controls  whether  or not messages are saved in the "$postponed"
              mailbox when you elect not to send immediately.



       postponed
              Type: path
              Default: "~/postponed"

              Mutt allows you to indefinitely  "postpone  sending  a  message"
              which  you  are editing.  When you choose to postpone a message,
              Mutt saves it in the mailbox specified by this  variable.   Also
              see the "$postpone" variable.



       preconnect
              Type: string
              Default: ""

              If  set,  a shell command to be executed if mutt fails to estab-
              lish a connection to the server. This is useful for  setting  up
              secure  connections,  e.g. with ssh(1). If the command returns a
              nonzero status, mutt gives up opening the server. Example:

              preconnect="ssh  -f  -q  -L  1234:mailhost.net:143  mailhost.net
              sleep 20 < /dev/null > /dev/null"

              Mailbox  'foo'  on  mailhost.net  can now be reached as '{local-
              host:1234}foo'.

              NOTE: For this example to work, you must be able to  log  in  to
              the remote machine without having to enter a password.



       print
              Type: quadoption
              Default: ask-no

              Controls whether or not Mutt asks for confirmation before print-
              ing.  This is useful for people (like me) who  accidentally  hit
              "p" often.



       print_command
              Type: path
              Default: "lpr"

              This  specifies  the  command  pipe that should be used to print
              messages.



       print_decode
              Type: boolean
              Default: yes

              Used in connection with  the  print-message  command.   If  this
              option is set, the message is decoded before it is passed to the
              external command specified by $print_command.  If this option is
              unset,  no processing will be applied to the message when print-
              ing it.  The latter setting may be useful if you are using  some
              advanced  printer filter which is able to properly format e-mail
              messages for printing.



       print_split
              Type: boolean
              Default: no

              Used in connection with  the  print-message  command.   If  this
              option  is  set, the command sepcified by $print_command is exe-
              cuted once for each message which is to  be  printed.   If  this
              option is unset, the command specified by $print_command is exe-
              cuted only once, and all the messages are concatenated,  with  a
              form feed as the message separator.

              Those  who use the enscript(1) program's mail-printing mode will
              most likely want to set this option.



       prompt_after
              Type: boolean
              Default: yes

              If you use an external  "$pager",  setting  this  variable  will
              cause  Mutt  to  prompt  you  for a command when the pager exits
              rather than returning to the index menu.  If  unset,  Mutt  will
              return to the index menu when the external pager exits.



       query_command
              Type: path
              Default: ""

              This  specifies  the command that mutt will use to make external
              address queries.  The string should contain a %s, which will  be
              substituted  with  the query string the user types.  See "query"
              for more information.



       quit
              Type: quadoption
              Default: yes

              This variable controls whether "quit" and "exit"  actually  quit
              from  mutt.  If it set to yes, they do quit, if it is set to no,
              they have no effect, and if it is set to ask-yes or ask-no,  you
              are prompted for confirmation when you try to quit.



       quote_regexp
              Type: regular expression
              Default: "^([ \t]*[|>:}#])+"

              A  regular  expression  used  in the internal-pager to determine
              quoted sections of text in the body of a message.

              Note: In order to use  the  quotedx  patterns  in  the  internal
              pager, you need to set this to a regular expression that matches
              exactly the quote characters at the beginning of quoted lines.



       read_inc
              Type: number
              Default: 10

              If set to a value greater than 0, Mutt will display  which  mes-
              sage  it is currently on when reading a mailbox.  The message is
              printed after read_inc messages have been read (e.g., if set  to
              25, Mutt will print a message when it reads message 25, and then
              again when it gets to message 50).  This variable  is  meant  to
              indicate  progress  when  reading large mailboxes which may take
              some time.  When set to 0, only a  single  message  will  appear
              before the reading the mailbox.

              Also see the "$write_inc" variable.



       read_only
              Type: boolean
              Default: no

              If set, all folders are opened in read-only mode.



       realname
              Type: string
              Default: ""

              This variable specifies what "real" or "personal" name should be
              used when sending messages.

              By default, this is the GCOS field from /etc/passwd.  Note  that
              this variable will not be used when the user has set a real name
              in the $from variable.



       recall
              Type: quadoption
              Default: ask-yes

              Controls whether or not you are  prompted  to  recall  postponed
              messages when composing a new message.  Also see "$postponed".

              Setting this variable to "yes" is not generally useful, and thus
              not recommended.



       record
              Type: path
              Default: ""

              This specifies the file into which your outgoing messages should
              be  appended.  (This is meant as the primary method for saving a
              copy of your messages, but another way to do this is  using  the
              "my_hdr"  command to create a Bcc: field with your email address
              in it.)

              The value of $record is  overridden  by  the  "$force_name"  and
              "$save_name" variables, and the "fcc-hook" command.



       reply_regexp
              Type: regular expression
              Default: "^(re([\[0-9\]+])*|aw):[ \t]*"

              A  regular  expression  used  to  recognize  reply messages when
              threading and replying. The default  value  corresponds  to  the
              English "Re:" and the German "Aw:".



       reply_self
              Type: boolean
              Default: no

              If  unset  and  you  are replying to a message sent by you, Mutt
              will assume that you want to reply to  the  recipients  of  that
              message rather than to yourself.



       reply_to
              Type: quadoption
              Default: ask-yes

              If  set, Mutt will ask you if you want to use the address listed
              in the Reply-To: header field when replying to  a  message.   If
              you answer no, it will use the address in the From: header field
              instead.  This option is useful for reading a mailing list  that
              sets the Reply-To: header field to the list address and you want
              to send a private message to the author of a message.



       resolve
              Type: boolean
              Default: yes

              When set, the cursor will be automatically advanced to the  next
              (possibly  undeleted)  message  whenever a command that modifies
              the current message is executed.



       reverse_alias
              Type: boolean
              Default: no

              This variable controls whether or  not  Mutt  will  display  the
              "personal"  name from your aliases in the index menu if it finds
              an alias that matches the message's sender.  For example, if you
              have the following alias:




              alias juser abd30425@somewhere.net (Joe User)



              and then you receive mail which contains the following header:




              From: abd30425@somewhere.net



              It would be displayed in the index menu as "Joe User" instead of
              "abd30425@somewhere.net."  This is useful when the  person's  e-
              mail  address is not human friendly (like CompuServe addresses).



       reverse_name
              Type: boolean
              Default: no

              It may sometimes arrive that  you  receive  mail  to  a  certain
              machine, move the messages to another machine, and reply to some
              the messages from there.  If this variable is set,  the  default
              From:  line  of  the  reply  messages is built using the address
              where you received the messages you are  replying  to.   If  the
              variable  is  unset, the From: line will use your address on the
              current machine.



       reverse_realname
              Type: boolean
              Default: yes

              This variable fine-tunes the behaviour of the reverse_name  fea-
              ture.   When  it is set, mutt will use the address from incoming
              messages as-is, possibly including eventual real names.  When it
              is unset, mutt will override any such realnames with the setting
              of the realname variable.



       rfc2047_parameters
              Type: boolean
              Default: no

              When this variable is set,  Mutt  will  decode  RFC-2047-encoded
              MIME  parameters.  You  want to set this variable when mutt sug-
              gests  you  to  save  attachments  to  files  named  like  this:
              =?iso-8859-1?Q?file=5F=E4=5F991116=2Ezip?=

              When this variable is set interactively, the change doesn't have
              the desired effect before you have changed folders.

              Note that this use of RFC 2047's encoding is explicitly, prohib-
              ited  by the standard, but nevertheless encountered in the wild.
              Also note that setting this parameter will not have  the  effect
              that  mutt  generates this kind of encoding.  Instead, mutt will
              unconditionally use the encoding specified in RFC 2231.



       save_address
              Type: boolean
              Default: no

              If set, mutt will take the sender's full address when choosing a
              default   folder   for   saving   a  mail.  If  "$save_name"  or
              "$force_name" is set too, the selection of the fcc  folder  will
              be changed as well.



       save_empty
              Type: boolean
              Default: yes

              When  unset,  mailboxes  which contain no saved messages will be
              removed when closed (the  exception  is  "$spoolfile"  which  is
              never removed).  If set, mailboxes are never removed.

              Note:  This only applies to mbox and MMDF folders, Mutt does not
              delete MH and Maildir directories.



       save_name
              Type: boolean
              Default: no

              This variable controls  how  copies  of  outgoing  messages  are
              saved.   When set, a check is made to see if a mailbox specified
              by the recipient address exists (this is done by searching for a
              mailbox in the "$folder" directory with the username part of the
              recipient address).  If the mailbox exists, the outgoing message
              will be saved to that mailbox, otherwise the message is saved to
              the "$record" mailbox.

              Also see the "$force_name" variable.



       score
              Type: boolean
              Default: yes

              When this variable is unset, scoring is turned off.  This can be
              useful  to  selectively disable scoring for certain folders when
              the "$score_threshold_delete" variable and friends are used.



       score_threshold_delete
              Type: number
              Default: -1

              Messages which have been assigned a score equal to or lower than
              the value of this variable are automatically marked for deletion
              by mutt.  Since mutt scores are always greater than or equal  to
              zero,  the  default  setting  of this variable will never mark a
              message for deletion.



       score_threshold_flag
              Type: number
              Default: 9999

              Messages wich have been assigned a score greater than  or  equal
              to this variable's value are automatically marked "flagged".



       score_threshold_read
              Type: number
              Default: -1

              Messages which have been assigned a score equal to or lower than
              the value of this variable are automatically marked as  read  by
              mutt.   Since  mutt  scores  are always greater than or equal to
              zero, the default setting of this variable  will  never  mark  a
              message read.



       send_charset
              Type: string
              Default: "us-ascii:iso-8859-1:utf-8"

              A  list  of  character sets for outgoing messages. Mutt will use
              the first character set into which the  text  can  be  converted
              exactly.   If  your  "$charset" is not iso-8859-1 and recipients
              may not understand UTF-8, it is advisable to include in the list
              an  appropriate  widely  used  standard  character  set (such as
              iso-8859-2, koi8-r or iso-2022-jp) either instead  of  or  after
              "iso-8859-1".



       sendmail
              Type: path
              Default: "/usr/sbin/sendmail -oem -oi"

              Specifies the program and arguments used to deliver mail sent by
              Mutt.  Mutt expects that the specified program interprets  addi-
              tional arguments as recipient addresses.



       sendmail_wait
              Type: number
              Default: 0

              Specifies the number of seconds to wait for the "$sendmail" pro-
              cess to finish before giving up  and  putting  delivery  in  the
              background.

              Mutt interprets the value of this variable as follows:


              >0     number  of  seconds to wait for sendmail to finish before
                     continuing


              0      wait forever for sendmail to finish


              <0     always put sendmail in the background without waiting


              Note that if you specify a value other than 0, the output of the
              child process will be put in a temporary file.  If there is some
              error, you will be informed as to where to find the output.



       shell
              Type: path
              Default: ""

              Command to use when spawning a subshell.  By default, the user's
              login shell from /etc/passwd is used.



       sig_dashes
              Type: boolean
              Default: yes

              If  set,  a  line  containing "-- " will be inserted before your
              "$signature".  It is strongly recommended  that  you  not  unset
              this  variable  unless your "signature" contains just your name.
              The reason for this is because many software  packages  use  "--
              \n" to detect your signature.  For example, Mutt has the ability
              to highlight the signature in a different color in  the  builtin
              pager.



       sig_on_top
              Type: boolean
              Default: no

              If set, the signature will be included before any quoted or for-
              warded text.  It is strongly recommended that  you  do  not  set
              this variable unless you really know what you are doing, and are
              prepared to take some heat from netiquette guardians.



       signature
              Type: path
              Default: "~/.signature"

              Specifies the filename of your signature, which is  appended  to
              all outgoing messages.   If the filename ends with a pipe ("|"),
              it is assumed that filename is a shell command and input  should
              be read from its stdout.



       simple_search
              Type: string
              Default: "~f %s | ~s %s"

              Specifies  how  Mutt  should  expand a simple search into a real
              search pattern.  A simple search is one that  does  not  contain
              any  of the ~ operators.  See "patterns" for more information on
              search patterns.

              For example, if you simply type joe at a search or limit prompt,
              Mutt will automatically expand it to the value specified by this
              variable.  For the default value it would be:

              ~f joe | ~s joe



       smart_wrap
              Type: boolean
              Default: yes

              Controls the display of lines longer then the  screen  width  in
              the  internal  pager.  If  set, long lines are wrapped at a word
              boundary.  If unset, lines are  simply  wrapped  at  the  screen
              edge. Also see the "$markers" variable.



       smileys
              Type: regular expression
              Default: "(>From )|(:[-^]?[][)(><}{|/DP])"

              The  pager  uses  this variable to catch some common false posi-
              tives of "$quote_regexp", most notably smileys in the  beginning
              of a line



       sleep_time
              Type: number
              Default: 1

              Specifies  time,  in  seconds, to pause while displaying certain
              informational messages, while moving from folder to  folder  and
              after  expunging  messages from the current folder.  The default
              is to pause one second, so a value of zero for this option  sup-
              presses the pause.



       sort
              Type: sort order
              Default: date

              Specifies  how to sort messages in the index menu.  Valid values
              are:




                 date or date-sent
                 date-received
                 from
                 mailbox-order (unsorted)
                 score
                 size
                 subject
                 threads
                 to



              You may optionally use the reverse- prefix  to  specify  reverse
              sorting order (example: set sort=reverse-date-sent).



       sort_alias
              Type: sort order
              Default: alias

              Specifies  how  the entries in the `alias' menu are sorted.  The
              following are legal values:




                 address (sort alphabetically by email address)
                 alias (sort alphabetically by alias name)
                 unsorted (leave in order specified in .muttrc)





       sort_aux
              Type: sort order
              Default: date

              When sorting by threads, this variable controls how threads  are
              sorted in relation to other threads, and how the branches of the
              thread trees are sorted.  This can be  set  to  any  value  that
              "$sort"  can,  except  threads (in that case, mutt will just use
              date-sent).  You can also specify the last- prefix  in  addition
              to the reverse- prefix, but last- must come after reverse-.  The
              last- prefix causes messages to be sorted against  its  siblings
              by  which has the last descendant, using the rest of sort_aux as
              an ordering.  For  instance,  set  sort_aux=last-  date-received
              would  mean  that if a new message is received in a thread, that
              thread becomes the last one displayed (or the first, if you have
              set  sort=reverse-threads.)  Note:  For  reversed  "$sort" order
              $sort_aux is reversed again (which is not the right thing to do,
              but kept to not break any existing configuration setting).



       sort_browser
              Type: sort order
              Default: subject

              Specifies  how to sort entries in the file browser.  By default,
              the entries are sorted alphabetically.  Valid values:




                 alpha (alphabetically)
                 date
                 size
                 unsorted



              You may optionally use the reverse- prefix  to  specify  reverse
              sorting order (example: set sort_browser=reverse-date).



       sort_re
              Type: boolean
              Default: yes

              This  variable  is  only  useful  when  sorting  by threads with
              "$strict_threads" unset.  In that case, it changes the heuristic
              mutt uses to thread messages by subject.  With sort_re set, mutt
              will only attach a message as the child of  another  message  by
              subject  if  the subject of the child message starts with a sub-
              string matching the setting of  "$reply_regexp".   With  sort_re
              unset,  mutt  will attach the message whether or not this is the
              case, as long as the non-"$reply_regexp" parts of both  messages
              are identical.



       spoolfile
              Type: path
              Default: ""

              If  your spool mailbox is in a non-default place where Mutt can-
              not find it, you can specify its location  with  this  variable.
              Mutt  will  automatically  set this variable to the value of the
              environment variable $MAIL if it is not set.



       status_chars
              Type: string
              Default: "-*%A"

              Controls the characters used by the  "%r"  indicator  in  "$sta-
              tus_format".  The  first  character  is used when the mailbox is
              unchanged. The second is used when the mailbox has been changed,
              and  it  needs  to  be  resynchronized. The third is used if the
              mailbox is in read-only mode, or if  the  mailbox  will  not  be
              written  when  exiting  that  mailbox (You can toggle whether to
              write changes to a  mailbox  with  the  toggle-write  operation,
              bound  by  default  to "%"). The fourth is used to indicate that
              the current folder has been opened in attach- message mode (Cer-
              tain operations like composing a new mail, replying, forwarding,
              etc. are not permitted in this mode).



       status_format
              Type: string
              Default: "-%r-Mutt: %f [Msgs:%?M?%M/?%m%?n? New:%n?%?o? Old:%o?%?d? Del:%d?%?F? Flag:%F?%?t? Tag:%t?%?p? Post:%p?%?b? Inc:%b?%?l? %l?]---(%s/%S)-%>-(%P)---"

              Controls the format of the status line displayed  in  the  index
              menu.   This  string  is similar to "$index_format", but has its
              own set of printf()-like sequences:



              %b     number of mailboxes with new mail *


              %d     number of deleted messages *


              %h     local hostname


              %f     the full pathname of the current mailbox


              %F     number of flagged messages *


              %l     size (in bytes) of the current mailbox *


              %L     size (in bytes) of the messages shown (i.e., which  match
                     the current limit) *


              %m     the number of messages in the mailbox *


              %M     the  number of messages shown (i.e., which match the cur-
                     rent limit) *


              %n     number of new messages in the mailbox *


              %o     number of old unread messages


              %p     number of postponed messages *


              %P     percentage of the way through the index


              %r     modified/read-only/won't-write/attach-message  indicator,
                     according to $status_chars


              %s     current sorting mode ($sort)


              %S     current aux sorting method ($sort_aux)


              %t     number of tagged messages *


              %u     number of unread messages *


              %v     Mutt version string


              %V     currently active limit pattern, if any *


              %>X    right justify the rest of the string and pad with "X"


              %|X    pad to the end of the line with "X"


              * = can be optionally printed if nonzero

              Some  of  the  above sequences can be used to optionally print a
              string if their value is nonzero.  For  example,  you  may  only
              want  to  see  the  number  of flagged messages if such messages
              exist, since zero is not particularly meaningful.  To optionally
              print  a  string based upon one of the above sequences, the fol-
              lowing construct is used

              %?<sequence_char>?<optional_string>?

              where sequence_char is a character from  the  table  above,  and
              optional_string  is  the  string  you would like printed if sta-
              tus_char is nonzero.  optional_string may contain other sequence
              as well as normal text, but you may not nest optional strings.

              Here is an example illustrating how to optionally print the num-
              ber of new messages in a mailbox: %?n?%n new messages.?

              Additionally you can switch between two strings, the first  one,
              if  a value is zero, the second one, if the value is nonzero, by
              using            the            following             construct:
              %?<sequence_char>?<if_string>&<else_string>?

              You  can  additionally  force  the  result  of  any  printf-like
              sequence to be lowercase by  prefixing  the  sequence  character
              with  an  underscore (_) sign.  For example, if you want to dis-
              play the local hostname in lowercase, you would use: %_h



       status_on_top
              Type: boolean
              Default: no

              Setting this variable causes the "status bar" to be displayed on
              the first line of the screen rather than near the bottom.



       strict_threads
              Type: boolean
              Default: no

              If  set,  threading  will only make use of the "In-Reply-To" and
              "References" fields when you "$sort"  by  message  threads.   By
              default,  messages with the same subject are grouped together in
              "pseudo threads."  This may not always be desirable, such as  in
              a  personal  mailbox where you might have several unrelated mes-
              sages with the subject "hi" which will get grouped together.



       suspend
              Type: boolean
              Default: yes

              When unset, mutt won't stop when the user presses the terminal's
              susp  key,  usually  "control-Z". This is useful if you run mutt
              inside an xterm using a command like xterm -e mutt.



       text_flowed
              Type: boolean
              Default: no

              When set, mutt will generate text/plain;  format=flowed  attach-
              ments.   This  format is easier to handle for some mailing soft-
              ware, and generally just looks like ordinary text.  To  actually
              make  use of this format's features, you'll need support in your
              editor.

              Note that $indent_string is ignored when this option is set.



       thread_received
              Type: boolean
              Default: no

              When set, mutt uses the date received rather than the date  sent
              to thread messages by subject.



       thorough_search
              Type: boolean
              Default: no

              Affects  the  ~b  and  ~h search operations described in section
              "patterns" above.  If set, the headers and attachments  of  mes-
              sages  to  be  searched are decoded before searching.  If unset,
              messages are searched as they appear in the folder.



       tilde
              Type: boolean
              Default: no

              When set, the internal-pager will pad blank lines to the  bottom
              of the screen with a tilde (~).



       timeout
              Type: number
              Default: 600

              This  variable controls the number of seconds Mutt will wait for
              a key to be pressed in the  main  menu  before  timing  out  and
              checking  for new mail.  A value of zero or less will cause Mutt
              not to ever time out.



       tmpdir
              Type: path
              Default: ""

              This variable allows you to specify where Mutt  will  place  its
              temporary files needed for displaying and composing messages.



       to_chars
              Type: string
              Default: " +TCFL"

              Controls  the  character used to indicate mail addressed to you.
              The first character is  the  one  used  when  the  mail  is  NOT
              addressed  to your address (default: space).  The second is used
              when you are the only recipient of  the  message  (default:  +).
              The  third  is when your address appears in the TO header field,
              but you are not the only recipient of the message (default:  T).
              The  fourth  character is used when your address is specified in
              the CC header field, but you are not the  only  recipient.   The
              fifth  character  is used to indicate mail that was sent by you.
              The sixth character is used to indicate when a mail was sent  to
              a mailing-list you subscribe to (default: L).



       tunnel
              Type: string
              Default: ""

              Setting  this  variable will cause mutt to open a pipe to a com-
              mand instead of a raw socket. You may be able to use this to set
              up   preauthenticated  connections  to  your  IMAP/POP3  server.
              Example:

              tunnel="ssh -q mailhost.net /usr/local/libexec/imapd"

              NOTE: For this example to work you must be able to log in to the
              remote machine without having to enter a password.



       use_8bitmime
              Type: boolean
              Default: no

              Warning: do not set this variable unless you are using a version
              of sendmail which supports the -B8BITMIME flag (such as sendmail
              8.8.x) or you may not be able to send mail.

              When  set, Mutt will invoke "$sendmail" with the -B8BITMIME flag
              when sending 8-bit messages to enable ESMTP negotiation.



       use_domain
              Type: boolean
              Default: yes

              When set, Mutt will qualify all local  addresses  (ones  without
              the  @host portion) with the value of "$hostname".  If unset, no
              addresses will be qualified.



       use_from
              Type: boolean
              Default: yes

              When set, Mutt will generate the `From:' header field when send-
              ing  messages.  If unset, no `From:' header field will be gener-
              ated unless the user explicitly sets one using the "my_hdr" com-
              mand.



       use_ipv6
              Type: boolean
              Default: yes

              When set, Mutt will look for IPv6 addresses of hosts it tries to
              contact.  If this option is unset, Mutt will restrict itself  to
              IPv4 addresses.  Normally, the default should work.



       user_agent
              Type: boolean
              Default: yes

              When  set,  mutt will add a "User-Agent" header to outgoing mes-
              sages, indicating which version of mutt was used  for  composing
              them.



       visual
              Type: path
              Default: ""

              Specifies  the  visual  editor  to invoke when the ~v command is
              given in the builtin editor.



       wait_key
              Type: boolean
              Default: yes

              Controls whether Mutt will ask you to press a key  after  shell-
              escape, pipe-message, pipe-entry, print-message, and print-entry
              commands.

              It is also used when viewing attachments with "auto_view",  pro-
              vided  that  the corresponding mailcap entry has a needsterminal
              flag, and the external program is interactive.

              When set, Mutt will always ask for a key. When unset, Mutt  will
              wait  for a key only if the external command returned a non-zero
              status.



       weed
              Type: boolean
              Default: yes

              When set, mutt will weed headers when when displaying,  forward-
              ing, printing, or replying to messages.



       wrap_search
              Type: boolean
              Default: yes

              Controls whether searches wrap around the end of the mailbox.

              When set, searches will wrap around the first (or last) message.
              When unset, searches will not wrap.



       wrapmargin
              Type: number
              Default: 0

              Controls the margin left at the right side of the terminal  when
              mutt's pager does smart wrapping.



       write_inc
              Type: number
              Default: 10

              When  writing  a  mailbox,  a  message  will  be  printed  every
              write_inc messages to indicate progress.  If set to  0,  only  a
              single message will be displayed before writing a mailbox.

              Also see the "$read_inc" variable.



       write_bcc
              Type: boolean
              Default: yes

              Controls  whether  mutt writes out the Bcc header when preparing
              messages to be sent.  Exim users may wish to use this.
