Mutt is a text-based mail client renowned for its powerful features. Mutt, though over a decade old, remains the mail client of choice for a great number of power-users. Unfortunately, a default Mutt install is plagued by complex keybindings along with a daunting amount of documentation. This guide will help the average user get Mutt up and running, and begin customizing it to their particular needs.


Mutt focuses primarily on being a Mail User Agent (MUA), and was originally written to view mail. Later implementations added for retrieval, sending, and filtering mail are simplistic compared to other mail applications and, as such, users may wish to use external applications to extend Mutt's capabilities.

Nevertheless, the Archlinux Template:Package Official package is compiled with IMAP, POP3 and SMTP support, removing the necessity for external applications.

This article covers using both native IMAP sending and retrieval, and a setup depending on OfflineIMAP or getmail (POP3) to retrieve mail, procmail to filter it in the case of POP3, and msmtp to send it.


Install Mutt:

# pacman -S mutt

Optionally install external helper applications for an IMAP setup:

# pacman -S offlineimap msmtp

Or if using POP3:

# pacman -S getmail procmail



This section covers IMAP, #POP3, #Maildir and #SMTP configuration.

Note that Mutt will recognize two locations for its configuration file; Template:Filename and Template:Filename. Either location will work.


Native and external setups

Using native IMAP support

The pacman version of Mutt is compiled with IMAP support. At the very least you need to have 4 lines in your muttrc file to be able to access your mail.

set imap_user=USERNAME

Continuing with the previous example, remember that gmail requires your full email address (this is not standard):


If unset, the password will be prompted for.

set imap_pass=SECRET

Instead of a local directory which contains all your mail (and directories), use your server (and the highest folder in the hierarchy, if needed).

set folder=imap[s]://imap.server.domain[:port]/[folder/]

You don't have to use a folder, but it might be convenient if you have all your other folders inside your INBOX, for example. Whatever you set here as your folder can be accessed later in Mutt with just an equal sign (=). Example:

set folder=imaps://

You can now use '=' or '+' as a substitution for the full Template:Codeline path that was configured above. For example:

set spoolfile=+INBOX

Any imap folders that should be checked regularly for new mail should be listed here:

mailboxes =INBOX =family
mailboxes imaps:// imaps://

Alternatively, check for all subscribed IMAP folders (as if all were added with a Template:Codeline line):

set imap_check_subscribed

These two versions are equivalent, but the first is much more convenient. Also, newer Mutt versions are configured by default to include a macro bound to the 'y' key which will allow you to change to any of the folders listed under mailboxes.


Using these options, you'll be able to start mutt, enter your IMAP password, and start reading your mail. Here is a muttrc snippet (for Gmail) with some other lines you might consider adding for better IMAP support.

set folder      = imaps://
set imap_user   =
set imap_pass   = your-imap-password
set spoolfile   = +INBOX
mailboxes       = +INBOX

# store message headers locally to speed things up
set header_cache = ~/.mutt/hcache

# specify where to save and/or look for postponed messages
set postponed = +[Gmail]/Drafts

# allow mutt to open new imap connection automatically
unset imap_passive

# keep imap connection alive by polling intermittently (time in seconds)
set imap_keepalive = 300

# how often to check for new mail (time in seconds)
set mail_check = 120

External IMAP support

While IMAP-functionality is built into Mutt, it does not download mail for offline-use. The OfflineIMAP article describes how to download your emails to a local folder which can then be processed by Mutt.

Consider using applications such as spamassassin or imapfilter to sort mail.


Retrieving and sorting mail with external applications

Retrieving mail

Create the directory ~/.getmail/. Open the file ~/.getmail/getmailrc in your favorite text editor.

Here is an example getmailrc used with a gmail account.

type = SimplePOP3SSLRetriever
server =
username =
port = 995
password = password

type = Maildir
path = ~/mail/

You can tweak this to your POP3 service's specification.

As you can see ~/.getmail/getmailrc contains sensitive information (namely, email account passwords in plain text). You will want to change access permissions to the directory so only the owner can see it:

$ chmod 700 ~/.getmail

For this guide we will be storing our mail in the maildir format. The two main mailbox formats are mbox and maildir. The main difference between the two is that mbox is one file, with all of your mails and their headers stored in it, whereas a maildir is a directory tree. Each mail is its own file, which will often speed things up.

A maildir is just a folder with the folders cur, new and tmp in it.

   mkdir -p ~/mail/{cur,new,tmp}

Now, run getmail. If it works fine, you can create a cronjob for getmail to run every n hours/minutes. Type crontab -e to edit cronjobs, and enter the following:

 */30 * * * * /usr/bin/getmail

That will run getmail every 30 minutes.

More than one Email account with getmail

By default, when you run getmail the program searches for the file getmailrc created as seen above. If you have more than one mail account you would like to get mail from, then you can create such a file for each email address, and then tell getmail to run using both of them. Obviously if you have two accounts and two files you can't have both of them called getmailrc. What you do is give them two different names, using myself as an example: I call one personal, and one university. These two files contain content relevant to my personal mail, and my university work mail respectively. Then to get getmail to work on these two files, instead of searching for getmailrc(default), I use the --rcfile switch like so: getmail --rcfile university --rcfile personal This can work with more files if you have more email accounts, just make sure each file is in the .getmail directory and make sure to alter the cronjob to run the command with the --rcfile switches. E.g.

 */30 * * * * /usr/bin/getmail --rcfile university --rcfile personal

Obviously you can call your files whatever you want, providing you include them in the cronjob or shell command, and they are in the .getmail/ directory, getmail will fetch mail from those two accounts.

Sorting mail

Procmail is an extremely powerful sorting tool. For the purposes of this wiki, we will do some primitive sorting to get started.

You must edit your getmailrc to pass retrieved mail to procmail:

type = MDA_external
path = /usr/bin/procmail

Now, open up .procmailrc in your favorite editor. The following will sort all mail from the happy-kangaroos mailing list, and all mail from your lovey-dovey friend in their own maildirs.


* ^To:

* ^From:

After you've saved your .procmailrc, run getmail and see if procmail succeeds in sorting your mail into the appropriate directories.

Note: One easy to make mistake with .procmailrc is the permission. procmail require it to have permission 644 and won't give meaningless error message if you don't.


Maildir is a generic and standardized format. Almost every MUA is able to handle Maildirs and Mutt's support is excellent. There are just a few simple things that you need to do to get Mutt to use them. Open your muttrc with and add the following lines:

set mbox_type=Maildir
set folder=$HOME/Mail
set spoolfile=+/INBOX
set header_cache=~/.hcache

This is a minimal Configuration that enables you to access your Maildir and checks for new local Mails in INBOX. This configuration also caches the headers of the eMails to speed up directory-listings. It might not be enabled in your build (but it sure is in the Arch-Package) Note that this does not affect OfflineIMAP in any way. It always syncs the all directories on a Server. spoolfile tells Mutt which local directories to poll for new Mail. You might want to add more Spoolfiles (for example the Directories of Mailing-Lists) and maybe other things. But this is subject to the Mutt manual and beyond the scope of this document.


Whether you use POP or IMAP to receive mail you will probably still send mail using SMTP.

Using native SMTP support

The pacman version of Mutt is also compiled with SMTP support. Just check the online manual muttrc, or man muttrc for more information.

For example:

set my_pass='mysecretpass'

set smtp_url=smtps://$my_user:$
set ssl_force_tls = yes

External SMTP support

An external SMTP agenta such as msmtp or SSMTP can also be used. This section exclusively covers configuring Mutt for msmtp.

Edit Mutt's configuration file or create it if unpresent: Template:File

Now, startup Template:Codeline:

$ mutt

You should see all the mail in Template:Filename. Press Template:Keypress to compose mail; it will use the editor defined by your Template:Codeline environment variable. If this variable is not set, type:

$ export EDITOR=editorbin

For testing purposes, address the letter to yourself. After you have written the letter, save and exit the editor. You will return to Mutt, which will now show information about your e-mail. Press Template:Keypress to send it.


Guides to get you started with using & customizing Mutt :

If you have any Mutt specific questions, feel free to ask in the irc channel.


You can install Template:Package AUR from the AUR for a fancier printing quality. In your muttrc file, insert:

set print_command="/usr/bin/muttprint %s -p {PrinterName}"

Signature block

Create a .signature in your home directory. Your signature will be appended at the end of your email.

Random signature

You can use fortune to add a random signature to mutt.

$ pacman -S fortune-mod

Create a fortune file and then add the following line to your .muttrc:

set signature="fortune pathtofortunefile"

Viewing URLs & opening Firefox

Your should start by creating a .mutt directory in $HOME if not done yet. There, create a file named macros. Insert the following:

 macro pager \cb <pipe-entry>'urlview'<enter> 'Follow links with urlview'

Then install urlview with:

pacman -S urlview

Create a .urlview in $HOME and insert the following:

REGEXP (((http|https|ftp|gopher)|mailto)[.:][^ >"\t]*|www\.[-a-z0-9.]+)[^ .,;\t>">\):]
COMMAND firefox %s 

When you read an email on the pager, hitting ctrl+b will list all the urls from the email. Navigate up or down with arrow keys and hit enter on the desired url. Firefox will start and go to the selected site.

  • Note - urlview has been moved to unsupported and is available in AUR here[1]
  • Note - If you have some problems with urlview due to Mutt's url encoding you can try
  • Note - If you'd like to see a short contextual preview of the content around each URL, try urlscan. The macro in your muttrc is the same as for urlview (except for the 'urlscan' command). There is no additional configuration required other than ensuring $BROWSER is set.

Mutt and Vim

  • To limit the width of text to 72 characters, edit your .vimrc file and add:
au BufRead /tmp/mutt-* set tw=72
  • Another choice is to use Vim's mail filetype plugin to enable other mail-centric options besides 72 character width. Edit Template:Filename, creating it if unpresent, and add:
augroup filetypedetect
  " Mail
  autocmd BufRead,BufNewFile *mutt-*              setfiletype mail
augroup END
  • To set a different tmp directory, e.g. ~/.tmp, add a line to your muttrc as follows:
set tmpdir="~/.tmp"
  • To reformat a modified text see the Vim context help
:h 10.7

Viewing HTML within a Vim/Mutt setup

It is possible to pass the html body to an external HTML program and then dump it, keeping email viewing uniform and unobtrusive. Two programs are described here: lynx and w3m.

Install lynx or w3m:

pacman -S lynx


pacman -S w3m

If ~/.mutt/mailcap does not exist you will need to create it and save the following to it.

text/html; lynx -dump %s; nametemplate=%s.html; copiousoutput

or, in case of w3m,

text/html; w3m -I %{charset} -T text/html; copiousoutput;

Edit muttrc and add the following,

set mailcap_path 	= ~/.mutt/mailcap

To automatically open HTML messages in lynx, add this additional line to the muttrc:

auto_view text/html

The beauty of this is, instead of seeing an html body as source or being opened by a separate program, in this case lynx, it gets parsed to Vim as html, any url links within the email can be displayed with Ctrl+b.

Mutt and GNU nano

nano is another nice console editor to use with Mutt.

To limit the width of text to 72 characters, edit your .nanorc file and add:

 set fill 72

Also, in muttrc file, you can specify the line to start editing so that you will skip the mail header:

 set editor="nano +7"

Tips & Tricks

Use Mutt to send mail from command line

Man pages will show all available commands and how to use them, but here are a couple of examples. You could use Mutt to send alerts, logs or some other system information, triggered by login through .bash_profile, or as a regular cron job.

Send a message:

mutt -s "Subject" < /var/log/somelog

Send a message with attachment:

mutt -s "Subject" -a somefile < /tmp/sometext.txt

How to display another email while composing

A common complaint with Mutt is that when composing a new mail (or reply), you cannot open another mail (i.e. for checking with another correspondant) without closing the current mail (postponing). The following describes a solution:

First, fire up Mutt as usual. Then, launch another terminal window. Now start a new Mutt with

mutt -R

This starts Mutt in read-only mode, and you can browse other emails at your convenience. It is strongly recommended to always launch a second Mutt in read-only mode, as conflicts will easily arise otherwise.

Now, this solution calls for a bit of typing, so we would like to automate this. The following works with Awesome, in other WM's or DE's similar solutions are probably available: just google how to add a key binding, and make the desired key execute

$TERM -e mutt -R 

where $TERM is your terminal.

As for Awesome: edit your rc.lua, and add the following on one of the first lines, after terminal = "yourTerminal" etc.

mailview = terminal .. " -e mutt -R"

This automatically uses your preferred terminal, ".." is concatenation in Lua. Note the space before -e.

Then add the following inside --{{{ Key bindings

awful.key({ modkey,           }, "m", function() awful.util.spawn(mailview) end),

Omit the final comma if this is the last line. You can, of course use another key than "m". Now, save&quit, and check your syntax with

awesome -k

If this is good, restart awesome and give it a try!

Now, a usage example: Launch mutt as usual. Start a new mail, and then press "Mod4"+"m". This opens your mailbox in a new terminal, and you can browse around and read other emails. Now, a neat bonus: exit this read-only-Mutt with "q", and the terminal window it created disappears!
