Mutt also supports a <span class="quote">“<span class="quote">batch</span>”</span> mode to send prepared
messages.  Simply redirect input from the file you wish to send.  For
example,
</p><pre class="screen">
mutt -s "data set for run #2" professor@bigschool.edu &lt; ~/run2.dat</pre><p>
will send a message to
<code class="literal">&lt;professor@bigschool.edu&gt;</code> with a subject of
<span class="quote">“<span class="quote">data set for run #2</span>”</span>.  In the body of the message will be
the contents of the file <span class="quote">“<span class="quote">~/run2.dat</span>”</span>.
</p><p>
An include file passed with <code class="literal">-i</code> will be used as the
body of the message.  When combined with <code class="literal">-E</code>, the
include file will be directly edited during message composition.  The
file will be modified regardless of whether the message is sent or
aborted.
</p><p>
A draft file passed with <code class="literal">-H</code> will be used as the
initial header and body for the message.  Multipart messages can be
used as a draft file.  When combined with <code class="literal">-E</code>, the
draft file will be updated to the final state of the message after
composition, regardless of whether the message is sent, aborted, or
even postponed.  Note that if the message is sent encrypted or signed,
the draft file will be saved that way too.
</p><p>
All files passed with <code class="literal">-a</code> <span class="emphasis"><em>file</em></span>
will be attached as a MIME part to the message. To attach a single or
several files, use <span class="quote">“<span class="quote">--</span>”</span> to separate files and recipient
addresses:
</p><pre class="screen">
mutt -a image.png -- some@one.org</pre><p>
or
</p><pre class="screen">
mutt -a *.png -- some@one.org</pre><div class="note"><h3 class="title">Note</h3><p>
The <code class="literal">-a</code> option must be last in the option list.
</p></div><p>
In addition to accepting a list of email addresses, Mutt also accepts a URL with
the <code class="literal">mailto:</code> schema as specified in RFC2368.  This is useful
when configuring a web browser to launch Mutt when clicking on mailto links.

Messages containing these codes are rare, but if this option is <span class="emphasis"><em>set</em></span>,
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

</p><pre class="screen">

and give it the same color as your attachment color (see also

in menus instead of highlighting the whole line.  On slow network or modem
links this will make response faster because there is less that has to

Default: (empty)</p></div><p>
This variable is a colon-separated list of character encoding
schemes for messages without character encoding indication.
Header field values and message body content without character encoding
indication would be assumed that they are written in one of this list.
By default, all the header fields and message body without any charset
indication are assumed to be in <span class="quote">“<span class="quote">us-ascii</span>”</span>.
</p><p>
For example, Japanese users might prefer this:

</p><pre class="screen">
set assumed_charset="iso-2022-jp:euc-jp:shift_jis:utf-8"
</pre><p>
However, only the first content is valid for the message body.

Default: (empty)</p></div><p>
This variable is a colon-separated list of character encoding
schemes for text file attachments. Mutt uses this setting to guess
which encoding files being attached are encoded in to convert them to
a proper character set given in <a class="link" href="reference.html#send-charset" title="3.295. send_charset">$send_charset</a>.
</p><p>
If <span class="emphasis"><em>unset</em></span>, the value of <a class="link" href="reference.html#charset" title="3.40. charset">$charset</a> will be used instead.
For example, the following configuration would work for Japanese
text handling:

</p><pre class="screen">
set attach_charset="iso-2022-jp:euc-jp:shift_jis:utf-8"
</pre><p>
Note: for Japanese users, <span class="quote">“<span class="quote">iso-2022-*</span>”</span> must be put at the head
of the value as shown above if included.

The default directory to save attachments from the <span class="quote">“<span class="quote">attachment</span>”</span> menu.
If it doesn't exist, Mutt will prompt to create the directory before

If this variable is <span class="emphasis"><em>unset</em></span>, when operating (saving, printing, piping,

attachments and will operate on them as a single attachment. The
<a class="link" href="reference.html#attach-sep" title="3.17. attach_sep">$attach_sep</a> separator is added after each attachment. When <span class="emphasis"><em>set</em></span>,
Mutt will operate on the attachments one by one.

accepts for the locale environment variable <code class="literal">$LC_TIME</code>.

This variable is to allow the attribution date format to be

Default: no</p></div><p>
When <span class="emphasis"><em>set</em></span>, Mutt assumes the presence of a List-Post header
means the recipient is subscribed to the list.  Unless the mailing list
is in the <span class="quote">“<span class="quote">unsubscribe</span>”</span> or <span class="quote">“<span class="quote">unlist</span>”</span> lists, it will be added
to the <span class="quote">“<span class="quote"><a class="link" href="configuration.html#subscribe">subscribe</a></span>”</span> list.  Parsing and checking these things slows
header reading down, so this option is disabled by default.

When <span class="emphasis"><em>set</em></span> along with <a class="link" href="reference.html#edit-headers" title="3.82. edit_headers">$edit_headers</a>, Mutt will skip the initial
send-menu (prompting for subject and recipients) and allow you to

When <span class="emphasis"><em>set</em></span>, Mutt will run <a class="link" href="reference.html#editor" title="3.83. editor">$editor</a> in the background during
message composition.  A landing page will display, waiting for
the <a class="link" href="reference.html#editor" title="3.83. editor">$editor</a> to exit.  The landing page may be exited, allowing
perusal of the mailbox, or even for other messages to be

Controls whether you will be asked to confirm bouncing messages.
If set to <span class="emphasis"><em>yes</em></span> you don't get asked if you want to bounce a
message. Setting this variable to <span class="emphasis"><em>no</em></span> is not generally useful,
and thus not recommended, because you are unable to bounce messages.

When this variable is <span class="emphasis"><em>set</em></span>, mutt will place the cursor at the beginning
of the current line in menus, even when the <a class="link" href="reference.html#arrow-cursor" title="3.9. arrow_cursor">$arrow_cursor</a> variable
is <span class="emphasis"><em>unset</em></span>, making it easier for blind persons using Braille displays to
follow these menus.  The option is <span class="emphasis"><em>unset</em></span> by default because many
visual terminals don't permit making the cursor invisible.

</p><p>
The default <code class="literal">"alpha"</code> setting of <a class="link" href="reference.html#sort-browser" title="3.355. sort_browser">$sort_browser</a> uses
locale-based sorting (using <code class="literal">strcoll(3)</code>), which ignores some
punctuation.  This can lead to some situations where the order
doesn't make intuitive sense.  In those cases, it may be
desirable to <span class="emphasis"><em>unset</em></span> this variable.

Default: yes</p></div><p>
When this variable is <span class="emphasis"><em>set</em></span>, the browser will attempt to keep
the cursor on the same mailbox when performing various functions.
These include moving up a directory, toggling between mailboxes

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 certificate can also
be saved in this file and further connections are automatically
accepted.
</p><p>
You can also manually add CA certificates in this file. Any server

When this variable is <span class="emphasis"><em>set</em></span>, the <code class="literal">&lt;change-folder&gt;</code> function
mailbox suggestion will start at the next folder in your <span class="quote">“<span class="quote"><a class="link" href="configuration.html#mailboxes" title="16. Monitoring Incoming Mail">mailboxes</a></span>”</span>

Character set your terminal uses to display and enter textual data.
It is also the fallback for <a class="link" href="reference.html#send-charset" title="3.295. send_charset">$send_charset</a>.
</p><p>
Upon startup Mutt tries to derive this value from environment variables
such as <code class="literal">$LC_CTYPE</code> or <code class="literal">$LANG</code>.
</p><p>
<span class="bold"><strong>Note:</strong></span> It should only be set in case Mutt isn't able to determine the

Default: no</p></div><p>
When this variable is <span class="emphasis"><em>set</em></span>, mutt will use file size attribute instead of
access time when checking for new mail in mbox and mmdf folders.
</p><p>
This variable is <span class="emphasis"><em>unset</em></span> by default and should only be enabled when
new mail detection for these folder types is unreliable or doesn't work.
</p><p>
Note that enabling this variable should happen before any <span class="quote">“<span class="quote"><a class="link" href="configuration.html#mailboxes" title="16. Monitoring Incoming Mail">mailboxes</a></span>”</span>
directives occur in configuration files regarding mbox or mmdf folders
because mutt needs to determine the initial new mail status of such a
mailbox by performing a fast mailbox scan when it is defined.
Afterwards the new mail status is tracked by file size changes.

<span class="bold"><strong>Note:</strong></span> this option only affects <span class="emphasis"><em>maildir</em></span> and <span class="emphasis"><em>MH</em></span> style
mailboxes.
</p><p>
When <span class="emphasis"><em>set</em></span>, Mutt will check for new mail delivered while the
mailbox 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
this variable is <span class="emphasis"><em>unset</em></span>, no check for new mail is performed
while the mailbox is open.

When defined, Mutt will recode commands in rc files from this
encoding to the current character set as specified by <a class="link" href="reference.html#charset" title="3.40. charset">$charset</a>
and aliases written to <a class="link" href="reference.html#alias-file" title="3.5. alias_file">$alias_file</a> from the current character set.
</p><p>
Please note that if setting <a class="link" href="reference.html#charset" title="3.40. charset">$charset</a> it must be done before
setting <a class="link" href="reference.html#config-charset" title="3.45. config_charset">$config_charset</a>.
</p><p>
Recoding should be avoided as it may render unconvertable
characters as question marks which can lead to undesired
side effects (for example in regular expressions).

When <span class="emphasis"><em>set</em></span>, Mutt will recurse inside multipart/alternatives while
performing attachment searching and counting (see <a class="link" href="mimesupport.html#attachments" title="6. Attachment Searching and Counting">attachments</a>).
</p><p>
Traditionally, multipart/alternative parts have simply represented
different encodings of the main content of the email.  Unfortunately,
some mail clients have started to place email attachments inside
one of alternatives.  Setting this will allow Mutt to find
and count matching attachments hidden there, and include them
in the index via %X or through ~X pattern matching.

When <span class="emphasis"><em>set</em></span>, Mutt will overlay the indicator, tree,

Setting this variable will cause Mutt to automatically enable and
disable encryption, based on whether all message recipient keys
can be located by Mutt.
</p><p>
When this option is enabled, Mutt will enable/disable encryption
each time the TO, CC, and BCC lists are edited.  If

When set, this modifies the behavior of <a class="link" href="reference.html#crypt-opportunistic-encrypt" title="3.59. crypt_opportunistic_encrypt">$crypt_opportunistic_encrypt</a>
to only search for "strong keys", that is, keys with full validity
according to the web-of-trust algorithm.  A key with marginal or no

For S/MIME, the behavior depends on the backend.  Classic S/MIME will
filter for certificates with the 't' (trusted) flag in the .index file.
The GPGME backend will use the same filters as with OpenPGP, and depends
on GPGME's logic for assigning the GPGME_VALIDITY_FULL and
GPGME_VALIDITY_ULTIMATE validity flag.

Default: yes</p></div><p>
When set, Mutt will display protected headers in the pager,
and will update the index and header cache with revised headers.
Protected headers are stored inside the encrypted or signed part of an
an email, to prevent disclosure or tampering.
For more information see https://github.com/autocrypt/protected-headers.
Currently Mutt only supports the Subject header.
</p><p>
Encrypted messages using protected headers often substitute the exposed
Subject header with a dummy value (see <a class="link" href="reference.html#crypt-protected-headers-subject" title="3.63. crypt_protected_headers_subject">$crypt_protected_headers_subject</a>).
Mutt will update its concept of the correct subject <span class="bold"><strong>after</strong></span> the
message is opened, i.e. via the <code class="literal">&lt;display-message&gt;</code> function.
If you reply to a message before opening it, Mutt will end up using
the dummy Subject header, so be sure to open such a message first.

When <a class="link" href="reference.html#crypt-protected-headers-read" title="3.61. crypt_protected_headers_read">$crypt_protected_headers_read</a> is set, and a message with a
protected Subject is opened, Mutt will save the updated Subject
into the header cache by default.  This allows searching/limiting
based on the protected Subject header if the mailbox is
re-opened, without having to re-open the message each time.
However, for mbox/mh mailbox types, or if header caching is not
set up, you would need to re-open the message each time the
mailbox was reopened before you could see or search/limit on the
protected subject again.
</p><p>
When this variable is set, Mutt additionally saves the protected
Subject back <span class="bold"><strong>in the clear-text message headers</strong></span>.  This
provides better usability, but with the tradeoff of reduced
security.  The protected Subject header, which may have
previously been encrypted, is now stored in clear-text in the
message headers.  Copying the message elsewhere, via Mutt or
external tools, could expose this previously encrypted data.
Please make sure you understand the consequences of this before
you enable this variable.

Controls whether or not the <span class="quote">“<span class="quote">Mail-Followup-To:</span>”</span> header field is
generated when sending mail.  When <span class="emphasis"><em>set</em></span>, Mutt will generate this
field when you are replying to a known mailing list, specified with
the <span class="quote">“<span class="quote"><a class="link" href="configuration.html#subscribe">subscribe</a></span>”</span> or <span class="quote">“<span class="quote"><a class="link" href="configuration.html#lists" title="14. Mailing Lists">lists</a></span>”</span> commands.

This field has two purposes.  First, preventing you from
receiving duplicate copies of replies to messages which you send
to mailing lists, and second, ensuring that you do get a reply
separately for any messages sent to known lists to which you are
not subscribed.
</p><p>
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

can be overridden using <span class="quote">“<span class="quote"><a class="link" href="configuration.html#my-hdr" title="17. User-Defined Headers">my_hdr</a></span>”</span> (including from a <span class="quote">“<span class="quote"><a class="link" href="configuration.html#send-hook" title="21. Change Settings Based Upon Message Recipients">send-hook</a></span>”</span>) and

Default: <span class="quote">“<span class="quote"><code class="literal">^[^,]*</code></span>”</span></p></div><p>
A regular expression used by mutt to parse the GECOS field of a password
entry when expanding the alias.  The default value
will return the string up to the first <span class="quote">“<span class="quote">,</span>”</span> encountered.
If the GECOS field contains a string like <span class="quote">“<span class="quote">lastname, firstname</span>”</span> then you
should set it to <span class="quote">“<span class="quote"><code class="literal">.*</code></span>”</span>.
</p><p>
This can be useful if you see the following behavior: you address an e-mail
to user ID <span class="quote">“<span class="quote">stevef</span>”</span> whose full name is <span class="quote">“<span class="quote">Steve Franklin</span>”</span>.  If mutt expands
<span class="quote">“<span class="quote">stevef</span>”</span> to <span class="quote">“<span class="quote">"Franklin" stevef@foo.bar</span>”</span> then you should set the <a class="link" href="reference.html#gecos-mask" title="3.108. gecos_mask">$gecos_mask</a> to
a regular expression that will match the whole name so mutt will expand
<span class="quote">“<span class="quote">Franklin</span>”</span> to <span class="quote">“<span class="quote">Franklin, Steve</span>”</span>.

Default: no</p></div><p>
When <span class="emphasis"><em>set</em></span>, this variable causes Mutt to include the header
of the message you are replying to into the edit buffer.
The <a class="link" href="reference.html#weed" title="3.404. weed">$weed</a> setting applies.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="header-cache"></a>3.111. header_cache</h3></div></div></div><div class="literallayout"><p>Type: path<br />
Default: (empty)</p></div><p>
This variable points to the header cache database.
If pointing to a directory Mutt will contain a header cache
database file per folder, if pointing to a file that file will
be a single global header cache. By default it is <span class="emphasis"><em>unset</em></span> so no header
caching will be used.
</p><p>
Header caching can greatly improve speed when opening POP, IMAP
MH or Maildir folders, see <span class="quote">“<span class="quote"><a class="link" href="optionalfeatures.html#caching" title="8. Local Caching">caching</a></span>”</span> for details.

Default: yes</p></div><p>
When mutt is compiled with qdbm, tokyocabinet, or kyotocabinet as header
cache backend, this option determines whether the database will be compressed.
Compression results in database files roughly being one fifth
of the usual diskspace, but the decompression can result in a
slower opening of cached folder(s) which in general is still
much faster than opening non header cached folders.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="header-cache-pagesize"></a>3.113. header_cache_pagesize</h3></div></div></div><div class="literallayout"><p>Type: number (long)<br />
Default: 16384</p></div><p>
When mutt is compiled with either gdbm or bdb4 as the header cache backend,
this option changes the database page size.  Too large or too small
values can waste space, memory, or CPU time. The default should be more
or less optimal for most use cases.

Default: no</p></div><p>
When <span class="emphasis"><em>set</em></span>, color header regexps behave like color body regexps:
color is applied to the exact text matched by the regexp.  When
<span class="emphasis"><em>unset</em></span>, color is applied to the entire header.
</p><p>
One use of this option might be to apply color to just the header labels.
</p><p>
See <span class="quote">“<span class="quote"><a class="link" href="configuration.html#color" title="11. Using Color and Mono Video Attributes">color</a></span>”</span> for more details.

When <span class="emphasis"><em>set</em></span>, help lines describing the bindings for the major functions
provided by each menu are displayed on the first line of the screen.
</p><p>
<span class="bold"><strong>Note:</strong></span> The binding will not be displayed correctly if the
function 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.

as the domain part (after <span class="quote">“<span class="quote">@</span>”</span>) for local email addresses as well as
Message-Id headers.
</p><p>
Its value is determined at startup as follows: the node's
hostname is first determined by the <code class="literal">uname(3)</code> function.  The
domain is then looked up using the <code class="literal">gethostname(2)</code> and
<code class="literal">getaddrinfo(3)</code> functions.  If those calls are unable to
determine the domain, the full value returned by uname is used.
Optionally, Mutt can be compiled with a fixed domain name in
which case a detected one is not used.
</p><p>
Starting in Mutt 2.0, the operations described in the previous
paragraph are performed after the muttrc is processed, instead of
beforehand.  This way, if the DNS operations are creating delays
at startup, you can avoid those by manually setting the value in
your muttrc.

When <span class="emphasis"><em>set</em></span>, Mutt will encode international domain names using
IDN.  Unset this if your SMTP server can handle newer (RFC 6531)
UTF-8 encoded domains. (IDN only)

Default: no</p></div><p>
This option replaces linear-white-space between encoded-word

<span class="quote">“<span class="quote">Subject:</span>”</span> field from being divided into multiple lines.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="ignore-list-reply-to"></a>3.131. ignore_list_reply_to</h3></div></div></div><div class="literallayout"><p>Type: boolean<br />
Default: no</p></div><p>
Affects the behavior of the <code class="literal">&lt;reply&gt;</code> function when replying to
messages from mailing lists (as defined by the <span class="quote">“<span class="quote"><a class="link" href="configuration.html#subscribe">subscribe</a></span>”</span> or
<span class="quote">“<span class="quote"><a class="link" href="configuration.html#lists" title="14. Mailing Lists">lists</a></span>”</span> commands).  When <span class="emphasis"><em>set</em></span>, if the <span class="quote">“<span class="quote">Reply-To:</span>”</span> field is
set to the same value as the <span class="quote">“<span class="quote">To:</span>”</span> field, Mutt assumes that the
<span class="quote">“<span class="quote">Reply-To:</span>”</span> 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 <span class="emphasis"><em>set</em></span>, use the <code class="literal"><a class="link" href="gettingstarted.html#list-reply">&lt;list-reply&gt;</a></code>
function; <code class="literal">&lt;group-reply&gt;</code> will reply to both the sender and the
list.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-authenticators"></a>3.132. imap_authenticators</h3></div></div></div><div class="literallayout"><p>Type: string<br />
Default: (empty)</p></div><p>
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 <span class="quote">“<span class="quote">login</span>”</span> or the right
side of an IMAP <span class="quote">“<span class="quote">AUTH=xxx</span>”</span> capability string, e.g. <span class="quote">“<span class="quote">digest-md5</span>”</span>, <span class="quote">“<span class="quote">gssapi</span>”</span>
or <span class="quote">“<span class="quote">cram-md5</span>”</span>. This option is case-insensitive. If it's
<span class="emphasis"><em>unset</em></span> (the default) mutt will try all available methods,
in order from most-secure to least-secure.
</p><p>
Example:

</p><pre class="screen">
set imap_authenticators="gssapi:cram-md5:login"
</pre><p>
<span class="bold"><strong>Note:</strong></span> Mutt will only fall back to other authentication methods if
the previous methods are unavailable. If a method is available but
authentication fails, mutt will not connect to the IMAP server.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-check-subscribed"></a>3.133. imap_check_subscribed</h3></div></div></div><div class="literallayout"><p>Type: boolean<br />
Default: no</p></div><p>
When <span class="emphasis"><em>set</em></span>, mutt will fetch the set of subscribed folders from
your server on connection, and add them to the set of mailboxes
it polls for new mail just as if you had issued individual <span class="quote">“<span class="quote"><a class="link" href="configuration.html#mailboxes" title="16. Monitoring Incoming Mail">mailboxes</a></span>”</span>
commands.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-condstore"></a>3.134. imap_condstore</h3></div></div></div><div class="literallayout"><p>Type: boolean<br />
Default: no</p></div><p>
When <span class="emphasis"><em>set</em></span>, mutt will use the CONDSTORE extension (RFC 7162)
if advertised by the server.  Mutt's current implementation is basic,
used only for initial message fetching and flag updates.
</p><p>
For some IMAP servers, enabling this will slightly speed up
downloading initial messages.  Unfortunately, Gmail is not one
those, and displays worse performance when enabled.  Your
mileage may vary.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-deflate"></a>3.135. imap_deflate</h3></div></div></div><div class="literallayout"><p>Type: boolean<br />
Default: no</p></div><p>
When <span class="emphasis"><em>set</em></span>, mutt will use the COMPRESS=DEFLATE extension (RFC
4978) if advertised by the server.
</p><p>
In general a good compression efficiency can be achieved, which
speeds up reading large mailboxes also on fairly good connections.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-delim-chars"></a>3.136. imap_delim_chars</h3></div></div></div><div class="literallayout"><p>Type: string<br />
Default: <span class="quote">“<span class="quote"><code class="literal">/.</code></span>”</span></p></div><p>
This contains the list of characters which you would like to treat
as folder separators for displaying IMAP paths. In particular it
helps in using the <span class="quote">“<span class="quote">=</span>”</span> shortcut for your <span class="emphasis"><em>folder</em></span> variable.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-fetch-chunk-size"></a>3.137. imap_fetch_chunk_size</h3></div></div></div><div class="literallayout"><p>Type: number (long)<br />
Default: 0</p></div><p>
When set to a value greater than 0, new headers will be
downloaded in groups of this many headers per request.  If you
have a very large mailbox, this might prevent a timeout and
disconnect when opening the mailbox, by sending a FETCH per set
of this many headers, instead of a single FETCH for all new
headers.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-headers"></a>3.138. imap_headers</h3></div></div></div><div class="literallayout"><p>Type: string<br />
Default: (empty)</p></div><p>
Mutt requests these header fields in addition to the default headers
(<span class="quote">“<span class="quote">Date:</span>”</span>, <span class="quote">“<span class="quote">From:</span>”</span>, <span class="quote">“<span class="quote">Sender:</span>”</span>, <span class="quote">“<span class="quote">Subject:</span>”</span>, <span class="quote">“<span class="quote">To:</span>”</span>, <span class="quote">“<span class="quote">Cc:</span>”</span>, <span class="quote">“<span class="quote">Message-Id:</span>”</span>,

servers before displaying the index menu. You may want to add more
headers for spam detection.
</p><p>
<span class="bold"><strong>Note:</strong></span> This is a space separated list, items should be uppercase
and not contain the colon, e.g. <span class="quote">“<span class="quote">X-BOGOSITY X-SPAM-STATUS</span>”</span> for the
<span class="quote">“<span class="quote">X-Bogosity:</span>”</span> and <span class="quote">“<span class="quote">X-Spam-Status:</span>”</span> header fields.

Default: no</p></div><p>
When <span class="emphasis"><em>set</em></span>, mutt will attempt to use the IMAP IDLE extension
to check for new mail in the current mailbox. Some servers
(dovecot was the inspiration for this option) react badly
to mutt's implementation. If your connection seems to freeze
up periodically, try unsetting this.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-keepalive"></a>3.140. imap_keepalive</h3></div></div></div><div class="literallayout"><p>Type: number<br />
Default: 300</p></div><p>
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 disconnected from your IMAP server due to inactivity.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-list-subscribed"></a>3.141. imap_list_subscribed</h3></div></div></div><div class="literallayout"><p>Type: boolean<br />
Default: no</p></div><p>
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 <code class="literal">&lt;toggle-subscribed&gt;</code> function.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-login"></a>3.142. imap_login</h3></div></div></div><div class="literallayout"><p>Type: string<br />
Default: (empty)</p></div><p>
Your login name on the IMAP server.
</p><p>
This variable defaults to the value of <a class="link" href="reference.html#imap-user" title="3.151. imap_user">$imap_user</a>.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-oauth-refresh-command"></a>3.143. imap_oauth_refresh_command</h3></div></div></div><div class="literallayout"><p>Type: string<br />
Default: (empty)</p></div><p>
The command to run to generate an OAUTH refresh token for
authorizing your connection to your IMAP server.  This command will be
run on every connection attempt that uses the OAUTHBEARER authentication
mechanism.  See <span class="quote">“<span class="quote"><a class="link" href="optionalfeatures.html#oauth" title="6. OAUTHBEARER Support">oauth</a></span>”</span> for details.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-pass"></a>3.144. imap_pass</h3></div></div></div><div class="literallayout"><p>Type: string<br />
Default: (empty)</p></div><p>
Specifies the password for your IMAP account.  If <span class="emphasis"><em>unset</em></span>, Mutt will
prompt you for your password when you invoke the <code class="literal">&lt;imap-fetch-mail&gt;</code> function
or try to open an IMAP folder.
</p><p>
<span class="bold"><strong>Warning</strong></span>: 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.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-passive"></a>3.145. imap_passive</h3></div></div></div><div class="literallayout"><p>Type: boolean<br />
Default: yes</p></div><p>
When <span class="emphasis"><em>set</em></span>, 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 for
user/password pairs on mutt invocation, or if opening the connection
is slow.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-peek"></a>3.146. imap_peek</h3></div></div></div><div class="literallayout"><p>Type: boolean<br />
Default: yes</p></div><p>
When <span class="emphasis"><em>set</em></span>, 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.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-pipeline-depth"></a>3.147. imap_pipeline_depth</h3></div></div></div><div class="literallayout"><p>Type: number<br />
Default: 15</p></div><p>
Controls the number of IMAP commands that may be queued up before they
are sent to the server. A deeper pipeline reduces the amount of time
mutt must wait for the server, and can make IMAP servers feel much
more responsive. But not all servers correctly handle pipelined commands,
so if you have problems you might want to try setting this variable to 0.
</p><p>
<span class="bold"><strong>Note:</strong></span> Changes to this variable have no effect on open connections.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-poll-timeout"></a>3.148. imap_poll_timeout</h3></div></div></div><div class="literallayout"><p>Type: number<br />
Default: 15</p></div><p>
This variable specifies the maximum amount of time in seconds
that mutt will wait for a response when polling IMAP connections
for new mail, before timing out and closing the connection.  Set
to 0 to disable timing out.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-qresync"></a>3.149. imap_qresync</h3></div></div></div><div class="literallayout"><p>Type: boolean<br />
Default: no</p></div><p>
When <span class="emphasis"><em>set</em></span>, mutt will use the QRESYNC extension (RFC 7162)
if advertised by the server.  Mutt's current implementation is basic,
used only for initial message fetching and flag updates.
</p><p>
Note: this feature is currently experimental.  If you experience
strange behavior, such as duplicate or missing messages please
file a bug report to let us know.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-servernoise"></a>3.150. imap_servernoise</h3></div></div></div><div class="literallayout"><p>Type: boolean<br />
Default: yes</p></div><p>
When <span class="emphasis"><em>set</em></span>, mutt will display warning messages from the IMAP
server as error messages. Since these messages are often
harmless, 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.
</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="imap-user"></a>3.151. imap_user</h3></div></div></div><div class="literallayout"><p>Type: string<br />

The name of the user whose mail you intend to access on the IMAP
server.

Default: no</p></div><p>
If set to <span class="quote">“<span class="quote">yes</span>”</span>, mutt will look for a mailcap entry with the
<span class="quote">“<span class="quote"><code class="literal">copiousoutput</code></span>”</span> flag set for <span class="emphasis"><em>every</em></span> 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.

Controls whether or not Mutt includes separately encrypted attachment
contents when replying.
</p><p>
This variable was added to prevent accidental exposure of encrypted
contents when replying to an attacker.  If a previously encrypted message
were attached by the attacker, they could trick an unwary recipient into
decrypting and including the message in their reply.

Default: <span class="quote">“<span class="quote"><code class="literal">&gt; </code></span>”</span></p></div><p>
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 fanatical netizens.
</p><p>
The value of this option is ignored if <a class="link" href="reference.html#text-flowed" title="3.380. text_flowed">$text_flowed</a> is set, because
the quoting mechanism is strictly defined for format=flowed.
</p><p>
This option is a format string, please see the description of
<a class="link" href="reference.html#index-format" title="3.157. index_format">$index_format</a> for supported <code class="literal">printf(3)</code>-style sequences.

This variable allows you to customize the message index display to
your personal taste.
</p><p>
<span class="quote">“<span class="quote">Format strings</span>”</span> are similar to the strings used in the C

Note that for mbox/mmdf, <span class="quote">“<span class="quote">%l</span>”</span> applies to the unprocessed message, and
for maildir/mh, the value comes from the <span class="quote">“<span class="quote">Lines:</span>”</span> header field when
present (the meaning is normally the same). Thus the value depends on
the encodings used in the different parts of the message and has little
meaning in practice.
</p><p>
<span class="quote">“<span class="quote">Soft-fill</span>”</span> deserves some explanation: Normal right-justification
will print everything to the left of the <span class="quote">“<span class="quote">%&gt;</span>”</span>, displaying padding and
whatever lies to the right only if there's room. By contrast,
soft-fill gives priority to the right-hand side, guaranteeing space
to display it and showing padding only if there's still room. If
necessary, soft-fill will eat text leftwards to make room for
rightward text.

this operation is more performance intensive, it defaults to

When <span class="emphasis"><em>unset</em></span>, the bottom entry of menus will never scroll up past
the bottom of the screen, unless there are less entries than lines.

Default: no</p></div><p>
If <span class="emphasis"><em>set</em></span>, mutt will clean out obsolete entries from the message cache when
the mailbox is synchronized. You probably only want to set it

Set this to a directory and mutt will cache copies of messages from
your IMAP and POP servers here. You are free to remove entries at any
time.
</p><p>
When setting this variable to a directory, mutt needs to fetch every
remote message only once and can perform regular expression searches
as fast as for local folders.

Default: no</p></div><p>
If <span class="emphasis"><em>set</em></span>, 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 <code class="literal">0xf8</code>, then this is treated as if the user had
pressed Esc then <span class="quote">“<span class="quote">x</span>”</span>.  This is because the result of removing the
high bit from <code class="literal">0xf8</code> is <code class="literal">0x78</code>, which is the ASCII character
<span class="quote">“<span class="quote">x</span>”</span>.

When <span class="emphasis"><em>unset</em></span>, mutt will mimic mh's behavior and rename deleted messages
to <span class="emphasis"><em>,&lt;old file name&gt;</em></span> in mh folders instead of really deleting
them. This leaves the message on disk but makes programs reading the folder
ignore it. If the variable is <span class="emphasis"><em>set</em></span>, the message files will simply be
deleted.

When <span class="emphasis"><em>set</em></span>, the message you are forwarding will be attached as a
separate <code class="literal">message/rfc822</code> 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

attachment's extension is not found in the mime.types file.
</p><p>
The string may contain a <span class="quote">“<span class="quote">%s</span>”</span>, which will be substituted with the

avoid adding your own.  If no <span class="quote">“<span class="quote">%s</span>”</span> is found in the string, Mutt will
append the attachment filename to the end of the string.
</p><p>
The command should output a single line containing the

Default: <span class="quote">“<span class="quote"><code class="literal">builtin</code></span>”</span></p></div><p>
This variable specifies which pager you would like to use to view
messages. The value <span class="quote">“<span class="quote">builtin</span>”</span> means to use the built-in pager, otherwise this
variable should specify the pathname of the external pager you would
like to use.
</p><p>
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.
</p><p>
When using an external pager, also see <a class="link" href="reference.html#prompt-after" title="3.263. prompt_after">$prompt_after</a> which defaults

Default: 0</p></div><p>
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 context).
</p><p>
This variable also specifies the amount of context given for search
results. If positive, this many lines will be given before a match,
if 0, the match will be top-aligned.

This variable controls the format of the one-line message <span class="quote">“<span class="quote">status</span>”</span>

Default: 0</p></div><p>
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 setting 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 <a class="link" href="reference.html#pager-index-lines" title="3.202. pager_index_lines">$pager_index_lines</a>, then the index will only use as
many lines as it needs.

Default: no</p></div><p>
If <span class="emphasis"><em>set</em></span>, mutt will automatically attempt to decrypt traditional PGP
messages whenever the user performs an operation which ordinarily would
result in the contents of the message being operated on.  For example,
if the user displays a pgp-traditional message which has not been manually
checked with the <code class="literal"><a class="link" href="gettingstarted.html#check-traditional-pgp">&lt;check-traditional-pgp&gt;</a></code> function, mutt will automatically
check the message for traditional pgp.

Default: no</p></div><p>
This option controls whether Mutt generates old-style inline
(traditional) PGP encrypted or signed messages under certain
circumstances.  This can be overridden by use of the pgp menu,
when inline is not required.  The GPGME backend does not support
this option.
</p><p>
Note that Mutt might automatically use PGP/MIME for messages
which consist of more than a single MIME part.  Mutt can be
configured to ask before sending PGP/MIME messages when inline
(traditional) would not work.
</p><p>
Also see the <a class="link" href="reference.html#pgp-mime-auto" title="3.225. pgp_mime_auto">$pgp_mime_auto</a> variable.

Default: yes</p></div><p>
If <span class="emphasis"><em>set</em></span>, mutt will check the status file descriptor output

PLAINTEXT occurs between the BEGIN_DECRYPTION and END_DECRYPTION
status codes.
</p><p>
If <span class="emphasis"><em>unset</em></span>, mutt will instead match the status fd output

Setting this variable will cause Mutt to always attempt to
create an inline (traditional) message when replying to a

and requires the agent be used for passphrase management.  Since
that version is increasingly prevalent, this variable now
defaults <span class="emphasis"><em>set</em></span>.

Mutt works with a GUI or curses pinentry program.  A TTY pinentry
should not be used.

Default: <span class="quote">“<span class="quote"><code class="literal">^([ \t]*[|&gt;:}#])+</code></span>”</span></p></div><p>
A regular expression used in the internal pager to determine quoted
sections of text in the body of a message. Quoted text may be filtered
out using the <code class="literal">&lt;toggle-quoted&gt;</code> command, or colored according to the
<span class="quote">“<span class="quote">color quoted</span>”</span> family of directives.
</p><p>
Higher levels of quoting may be colored differently (<span class="quote">“<span class="quote">color quoted1</span>”</span>,
<span class="quote">“<span class="quote">color quoted2</span>”</span>, etc.). The quoting level is determined by removing
the last character from the matched text and recursively reapplying
the regular expression until it fails to produce a match.
</p><p>
Match detection may be overridden by the <a class="link" href="reference.html#smileys" title="3.324. smileys">$smileys</a> regular expression.

If set to a value greater than 0, Mutt will display which message it
is currently on when reading a mailbox or when performing search actions
such as search and limit. The message is printed after
this many messages have been read or searched (e.g., if set to 25, Mutt will
print a message when it is at message 25, and then again when it gets
to message 50).  This variable is meant to indicate progress when
reading or searching large mailboxes which may take some time.
When set to 0, only a single message will appear before the reading
the mailbox.

If <span class="emphasis"><em>set</em></span>, when replying to a message, Mutt will use the address listed
in the Reply-to: header as the recipient of the reply.  If <span class="emphasis"><em>unset</em></span>,
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:

set when they are used as a draft file again.
</p><p>
The first time a draft file is saved, mutt will add a header,
X-Mutt-Resume-Draft to the saved file.  The next time the draft

This variable controls whether or not Mutt will display the <span class="quote">“<span class="quote">personal</span>”</span>
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:

</pre><p>
and then you receive mail which contains the following header:

</p><pre class="screen">
From: abd30425@somewhere.net
</pre><p>
It would be displayed in the index menu as <span class="quote">“<span class="quote">Joe User</span>”</span> instead of

It may sometimes arrive that you receive mail to a certain machine,
move the messages to another machine, and reply to some the messages

</p><p>
When it is <span class="emphasis"><em>unset</em></span>, Mutt will remove the real name part of a
matching address.  This allows the use of the email address
without having to also use what the sender put in the real name
field.
</p><p>
When it is <span class="emphasis"><em>set</em></span>, Mutt will use the matching address as-is.

When this variable is <span class="emphasis"><em>set</em></span>, Mutt will decode RFC2047-encoded MIME

</pre><p>
When this variable is <span class="emphasis"><em>set</em></span> interactively, the change won't be
active until you change folders.
</p><p>
Note that this use of RFC2047's encoding is explicitly
prohibited by the standard, but nevertheless encountered in the
wild.
</p><p>
Also note that setting this parameter will <span class="emphasis"><em>not</em></span> have the effect
that mutt <span class="emphasis"><em>generates</em></span> this kind of encoding.  Instead, mutt will
unconditionally use the encoding specified in RFC2231.

Mutt expects that the specified program interprets additional
arguments as recipient addresses.  Mutt appends all recipients after
adding a <code class="literal">--</code> delimiter (if not already present).  Additional
flags, such as for <a class="link" href="reference.html#use-8bitmime" title="3.396. use_8bitmime">$use_8bitmime</a>, <a class="link" href="reference.html#use-envelope-from" title="3.398. use_envelope_from">$use_envelope_from</a>,

this variable unless your signature contains just your name.  The
reason for this is because many software packages use <span class="quote">“<span class="quote">-- \n</span>”</span> to

Specifies the filename of your signature, which is appended to all
outgoing messages.   If the filename ends with a pipe (<span class="quote">“<span class="quote">|</span>”</span>), it is
assumed that filename is a shell command and input should be read from
its standard output.

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 <span class="quote">“<span class="quote">~</span>”</span> pattern
modifiers.  See <span class="quote">“<span class="quote"><a class="link" href="advancedusage.html#patterns" title="3. Patterns: Searching, Limiting and Tagging">patterns</a></span>”</span> for more information on search patterns.
</p><p>
For example, if you simply type <span class="quote">“<span class="quote">joe</span>”</span> at a search or limit prompt, Mutt
will automatically expand it to the value specified by this variable by
replacing <span class="quote">“<span class="quote">%s</span>”</span> with the supplied string.
For the default value, <span class="quote">“<span class="quote">joe</span>”</span> would be expanded to: <span class="quote">“<span class="quote">~f joe | ~s joe</span>”</span>.

OpenSSL. There is an index file which contains mailbox-address
keyid pairs, and which can be manually edited. This option points to
the location of the certificates.

This format string specifies a command which is used to decrypt
<code class="literal">application/x-pkcs7-mime</code> attachments.
</p><p>
The OpenSSL command formats have their own set of <code class="literal">printf(3)</code>-like sequences
similar to PGP's:

The default behavior of mutt is to use PGP on all auto-sign/encryption
operations. To override and to use OpenSSL instead this must be <span class="emphasis"><em>set</em></span>.
However, this has no effect while replying, since mutt will automatically
select the same application that was used to sign/encrypt the original
message.  (Note that this variable can be overridden by unsetting <a class="link" href="reference.html#crypt-autosmime" title="3.57. crypt_autosmime">$crypt_autosmime</a>.)

Default: (empty)</p></div><p>
Since for S/MIME there is no pubring/secring as with PGP, mutt has to handle
storage and retrieval of keys/certs by itself. This is very basic right now,
and stores keys and certificates in two different directories, both
named as the hash-value retrieved from OpenSSL. There is an index file
which contains mailbox-address keyid pair, and which can be manually
edited. This option points to the location of the private keys.

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 <a class="link" href="reference.html#sort" title="3.352. sort">$sort</a> can, except
<span class="quote">“<span class="quote">threads</span>”</span> (in that case, mutt will just use <span class="quote">“<span class="quote">date-sent</span>”</span>).  You can also
specify the <span class="quote">“<span class="quote">last-</span>”</span> prefix in addition to the <span class="quote">“<span class="quote">reverse-</span>”</span> prefix, but <span class="quote">“<span class="quote">last-</span>”</span>
must come after <span class="quote">“<span class="quote">reverse-</span>”</span>.  The <span class="quote">“<span class="quote">last-</span>”</span> prefix causes messages to be
sorted against its siblings by which has the last descendant, using
the rest of <a class="link" href="reference.html#sort-aux" title="3.354. sort_aux">$sort_aux</a> as an ordering.  For instance,

</p><pre class="screen">

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 <span class="quote">“<span class="quote"><code class="literal">set sort=reverse-threads</code></span>”</span>.)
</p><p>
Note: For reversed-threads <a class="link" href="reference.html#sort" title="3.352. sort">$sort</a>
order, <a class="link" href="reference.html#sort-aux" title="3.354. sort_aux">$sort_aux</a> is reversed again (which is not the right thing to do,

This variable controls what happens when multiple spam headers
are matched: if <span class="emphasis"><em>unset</em></span>, each successive header will overwrite any

</p><p>
* = can be optionally printed if nonzero
</p><p>
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 following construct is used:
</p><p>
<code class="literal">%?&lt;sequence_char&gt;?&lt;optional_string&gt;?</code>
</p><p>
where <span class="emphasis"><em>sequence_char</em></span> is a character from the table above, and
<span class="emphasis"><em>optional_string</em></span> is the string you would like printed if
<span class="emphasis"><em>sequence_char</em></span> is nonzero.  <span class="emphasis"><em>optional_string</em></span> <span class="bold"><strong>may</strong></span> contain
other sequences as well as normal text, but you may <span class="bold"><strong>not</strong></span> nest
optional strings.
</p><p>
Here is an example illustrating how to optionally print the number of
new messages in a mailbox:
</p><p>
<code class="literal">%?n?%n new messages.?</code>
</p><p>
You can also switch between two strings using the following construct:
</p><p>
<code class="literal">%?&lt;sequence_char&gt;?&lt;if_string&gt;&amp;&lt;else_string&gt;?</code>
</p><p>
If the value of <span class="emphasis"><em>sequence_char</em></span> is non-zero, <span class="emphasis"><em>if_string</em></span> will
be expanded, otherwise <span class="emphasis"><em>else_string</em></span> will be expanded.
</p><p>
You can force the result of any <code class="literal">printf(3)</code>-like sequence to be lowercase
by prefixing the sequence character with an underscore (<span class="quote">“<span class="quote">_</span>”</span>) sign.
For example, if you want to display the local hostname in lowercase,
you would use: <span class="quote">“<span class="quote"><code class="literal">%_h</code></span>”</span>.
</p><p>
If you prefix the sequence character with a colon (<span class="quote">“<span class="quote">:</span>”</span>) character, mutt
will replace any dots in the expansion by underscores. This might be helpful
with IMAP folders that don't like dots in folder names.

Setting this variable causes the <span class="quote">“<span class="quote">status bar</span>”</span> to be displayed on
the first line of the screen rather than near the bottom. If <a class="link" href="reference.html#help" title="3.115. help">$help</a>

default, messages with the same subject are grouped together in
<span class="quote">“<span class="quote">pseudo threads.</span>”</span>. This may not always be desirable, such as in a
personal mailbox where you might have several unrelated messages with
the subjects like <span class="quote">“<span class="quote">hi</span>”</span> which will get grouped together. See also
<a class="link" href="reference.html#sort-re" title="3.356. sort_re">$sort_re</a> for a less drastic way of controlling this
behavior.

<span class="emphasis"><em>susp</em></span> key, usually <span class="quote">“<span class="quote">^Z</span>”</span>. This is useful if you run mutt
inside an xterm using a command like <span class="quote">“<span class="quote"><code class="literal">xterm -e mutt</code></span>”</span>.

Default: no</p></div><p>
When <span class="emphasis"><em>set</em></span>, mutt will generate <span class="quote">“<span class="quote">format=flowed</span>”</span> bodies with a content type
of <span class="quote">“<span class="quote"><code class="literal">text/plain; format=flowed</code></span>”</span>.
This format is easier to handle for some mailing software, and generally
just looks like ordinary text.  To actually make use of this format's
features, you'll need support in your editor.
</p><p>
The option only controls newly composed messages.  Postponed messages,
resent messages, and draft messages (via -H on the command line) will
use the content-type of the source message.
</p><p>

</p><p>
Users searching attachments or for non-ASCII characters should <span class="emphasis"><em>set</em></span>

Default: (empty)</p></div><p>
Setting this variable will cause mutt to open a pipe to a command
instead of a raw socket. You may be able to use this to set up
preauthenticated connections to your IMAP/POP3/SMTP server. Example:

</p><pre class="screen">
set tunnel="ssh -q mailhost.net /usr/local/libexec/imapd"
</pre><p>
Note: For this example to work you must be able to log in to the remote
machine without having to enter a password.
</p><p>
When set, Mutt uses the tunnel for all remote connections.
Please see <span class="quote">“<span class="quote"><a class="link" href="optionalfeatures.html#account-hook" title="7. Managing Multiple Accounts">account-hook</a></span>”</span> in the manual for how to use different
tunnel commands per connection.

Default: yes</p></div><p>
When <span class="emphasis"><em>set</em></span>, Mutt will assume the <a class="link" href="reference.html#tunnel" title="3.392. tunnel">$tunnel</a> connection does not need
STARTTLS to be enabled.  It will also allow IMAP PREAUTH server
responses inside a <a class="link" href="reference.html#tunnel" title="3.392. tunnel">tunnel</a> to proceed.  This is appropriate if <a class="link" href="reference.html#tunnel" title="3.392. tunnel">$tunnel</a>
uses ssh or directly invokes the server locally.
</p><p>
When <span class="emphasis"><em>unset</em></span>, Mutt will negotiate STARTTLS according to the
<a class="link" href="reference.html#ssl-starttls" title="3.363. ssl_starttls">ssl_starttls</a> and <a class="link" href="reference.html#ssl-force-tls" title="3.361. ssl_force_tls">ssl_force_tls</a> variables.  If <a class="link" href="reference.html#ssl-force-tls" title="3.361. ssl_force_tls">ssl_force_tls</a> is
set, Mutt will abort connecting if an IMAP server responds with PREAUTH.
This setting is appropriate if <a class="link" href="reference.html#tunnel" title="3.392. tunnel">$tunnel</a> does not provide security and
could be tampered with by attackers.

Controls whether mutt writes out the <span class="quote">“<span class="quote">Bcc:</span>”</span> header when
preparing messages to be sent.  Some MTAs, such as Exim and
Courier, do not strip the <span class="quote">“<span class="quote">Bcc:</span>”</span> header; so it is advisable to
leave this unset unless you have a particular need for the header
to be in the sent message.
</p><p>
If mutt is set to deliver directly via SMTP (see <a class="link" href="reference.html#smtp-url" title="3.351. smtp_url">$smtp_url</a>),
this option does nothing: mutt will never write out the <span class="quote">“<span class="quote">Bcc:</span>”</span>
header in this case.
</p><p>
Note this option only affects the sending of messages.  Fcc'ed
copies of a message will always contain the <span class="quote">“<span class="quote">Bcc:</span>”</span> header if
one exists.

On Debian systems, exim4 and postfix strip BCC headers by
default. The above warning applies to exim3 users, see /etc/Muttrc.
