Linux Email Client Mutt Take Advantage Of Procmail And Fetchmail

Okay, I have written about Mutt before. Here I am going to specifically focus on two important tools to get integrated with it to help use this wonderful email client experience much better.

Procmail¹

This is a wonderful utility to help filter messages. Here is my .procmailrc

PATH=/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/home/bhaskar/bin/

MAILDIR=$HOME/.maildir/

DEFAULT=$MAILDIR

LOGFILE=$MAILDIR/log

SHELL=/bin/bash

:0

!^Content-Type: message/

!^Content-Type: multipart/

!^Content-Type: application/pgp

{

:0 fBw

• ^–—BEGIN PGP MESSAGE–—
• ^–—END PGP MESSAGE–—

formail \

-i “Content-Type: application/pgp; format=text; x-action=encrypt”

:0 fBw

• ^–—BEGIN PGP SIGNED MESSAGE–—
• ^–—BEGIN PGP SIGNATURE–—
• ^–—END PGP SIGNATURE–—

formail \

-i “Content-Type: application/pgp; format=text; x-action=sign” }

:0 h

• ^Subject:[ ]+\/(|send)[ ]+key pub\>.*

Basically to throw away useless junk mail permanently. You could write many other rules if you like to. Also, I have a key bind in my .muttrc to invoke it by hand from time to time.

macro index G "!fetchmail -a -m 'procmail -d %T'\r"

Fetchmail²

I have used it to fetch mail from the remote IMAP server. Here is my .fetchmailrc

#set daemon 120

set logfile /home/bhaskar/.fetchmail.log
     poll imap.your_mail_provider.com protocol imap
#poll imap.your_mail_provider.com protocol imap
          username "your_mail_address" password "your_password" is "bhaskar" here keep ssl;

          mda "/usr/bin/procmail -d %T"
