Mutt is a text based email client.

Installing Mutt

To install mutt, emerge it:

# emerge mutt

Essential Mutt Tips

This page was created as a good place for people to place their mutt configurations to share with others. These configuration settings go in the user's ~/.muttrc file.

set pager_stop

This turns off the default behavior of mutt where hitting space to scroll will automatically move to the next message when the end of the current message is reached. This is very annoying when scrolling in long emails like cron jobs.

  • ~/.mutt/lists

For this file follow the next steps:

  • Step 1:

Create a folder ~/.secret and inside that directory, create a file called .passwd. Add the following to it:

user1:    passwd1
user2:    passwd2

where "user1" and "user2" are identifiers for the accounts you added in the account_hooks and folder_hooks files, as well as at the start of the muttrc. Note that if your password contains semi-colons you'll have to escape them with three backslashes.

  • Step 2:

Now, encrypt the file with your gpg-key. If you don't have one, execute gpg --gen-key and create one. After that, don't forget to delete your unencrypted password storage:

$ gpg -r 0x<Your-ID-fingerprint> -o .passwd.gpg --encrypt .passwd
$ rm -f .passwd

Mutt postfix setup

Postfix is another popular and powerful mail transfer agent which is easier to configure than sendmail. Let's start a quick postfix mail transfer setup that will work with mutt. Set the sasl,berkdb USE flags to mail-mta/potsfix and mail-client/mutt in /etc/portage/package.use/:

# echo "mail-mta/postfix berkdb sasl" >> /etc/portage/package.use/mail
# echo "mail-client/mutt berkdb sasl" >> /etc/portage/package.use/mail
# emerge -uN1 mutt postfix

Edit /etc/postfix/ and add the following lines:

relayhost =
smtp_use_tls = yes
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/gmail_passwd
smtp_sasl_security_options = noanonymous

Create and edit the aforementioned authorization file: gmail_passwd:

# touch /etc/postfix/gmail_passwd
# echo "" >> /etc/postfix/gmail_passwd

Where <> is a gmail account and passwd is the account password. Convert gmail_passwd into Berkeley DB format, secure the file, and restart the postfix daemon:

# postmap /etc/postfix/gmail_passwd
# chown root:postfix /etc/postfix/gmail_passwd*
# chmod 0640 /etc/postfix/gmail_passwd*
# /etc/init.d/postfix restart
