[mutt] Configure mutt to receive email via IMAP and send via SMTP

“All mail clients suck. This one [mutt] just sucks less.” Michael Elkins, ca. 1995

Actually I have tried a lot of desktop email clients (viz., Outlook, thunderbird, seamonkey, sylpheed, pine, alpine, claws email, kmail, evolution, opera) and in the long run they all starts sucking at the RAM. Now to be precise, I must tell you that it’s not a full-fledged mail-transfer agent (MTA), but rather a mail user agent (MUA), i.e. just an email client just like those previously mentioned.

Step 1: Create a password file, say ~/.secret/.passwd. Enter the passwords in it as follows and save the file (don’t worry, we’re going to encrypt it soon!):

GMail:    passwd1
Yahoo:    passwd2

Step 2: Now encrypt the file with your gpg key (refer to the previous post for details). Don’t forget to delete the unencrypted file.

$ cd ~/.secret
$ gpg -e .passwd -o .passwd.gpg
$ rm -f .passwd

Step 3a: back to the home direcotory and modify the ~/.muttrc file: (you may equivalently do the same in ~/.mutt/muttrc)

# Process the password files first
#-------------------------------------
set my_tmpsecret=`gpg -o ~/.secret/.tmp -d ~/.secret/.passwd.gpg`
set my_gpass=`awk '/GMail:/ {print $2}' ~/.secret/.tmp`
set my_ypass=`awk '/Yahoo:/ {print $2}' ~/.secret/.tmp`
set my_del=`rm -f ~/.secret/.tmp`

Note: All user-defined variable must start with “my_”.

Step 3b: Now set up mutt for IMAP: (let’s say for GMail)

set imap_user="gmail.username@gmail.com"
set imap_pass=$my_gpass
set folder="imaps://gmail.username@imap.gmail.com:993/"
set spoolfile="+INBOX"
set postponed="+[Gmail]/Drafts"
set record=+[Gmail]/"Sent Mail"

Step 3c: Now let’s say we want to use Yahoo’s SMTP service to send emails: here’s how to set it up in ~/.muttrc:

set smtp_pass=$my_ypass
set smtp_url = "smtp://smtp.yahoo.com:587"  # using port 587 for TLS
set from="yahoo_username@yahoo.com"
set realname="Your Real_Name"

Step 3d: Set your favorite editor to compose emails next in ~/.muttrc (mine is vim, so….)

set editor='vim + -c "set textwidth=72" -c "set wrap" -c "set nocp" -c "?^$"'

Step 3e: Other necessary things to put in ~/.muttrc:

set header_cache=~/.mutt/cache/headers
set message_cachedir=~/.mutt/cache/bodies
set certificate_file=~/.mutt/certificates

Step 3f: Now time for some pretty color: (add these too to ~/.muttrc)

1 2 3 4 5 6 7 8

color  body            brightyellow    black    (((ht|f)tps?)|mailto):(//)?[^\ "\t]*|www\.[-a-z0-9.]+)[^\ .,;\t>">] mono   body            bold                     (((ht|f)tps?)|mailto):(//)?[^\ "\t]*|www\.[-a-z0-9.]+)[^\ .,;\t>">] color  body            brightmagenta   black   "[-a-z_0-9.]+@[-a-z_0-9.]+" mono   body            bold                    "[-a-z_0-9.]+@[-a-z_0-9.]+" color  body            brightyellow    black   "^Good signature" mono   body            bold                    "^Good signature" color  body            brightwhite     red     "^Bad signature from.*" mono   body            bold                    "^Bad signature from.*"

Step 3g: Some other customizations to put in ~/.muttrc:

set smart_wrap = yes
set sort = 'threads'
set sort_aux = 'last-date-received'
set imap_check_subscribed
#
ignore "Authentication-Results:"
ignore "DomainKey-Signature:"
ignore "DKIM-Signature:"
hdr_order Date From To Cc
#
set timeout=60	#Check for mail every minute
set mail_check=5

Step 3h: Now save the file in your home directory and make it readable by none but the current user (you of course!):

$ chmod 700 ~/.muttrc

Step 4:Next create the these two directories to save mutt related stuffs:

$ mkdir .mutt
$ mkdir .mutt/cache

Step 5:To render the HTML/etc messages correctly create another file ~/.mailcap with the following as its content make it readable by you only (use chmod as above)

text/html; lynx -dump %s ; copiousoutput

Change lynx to links/links2/elinks depending what you actually have on your system.

Things to do:
I still cannot use multiple IMAP inboxes at a time — the account-hook / folder-hook does not seem to work. I need to spend some more time on it.

Here’s how to use multiple IMAP accounts in mutt.
