Have been trying to make mutt work since dapper days, did not quite get it right. After seeing a post in ilugc mailing list today, was determined to try again. It did not take me any more than 5 minutes to get mutt working with exim4. Here are the steps..
 install exim4 (+exim4-base, exim4-config, exim4-daemon-light) and mutt
 configure exim4 as follows,
$ sudo dpkg-reconfigure exim4-config split configuration into small files ? YES choose "mail sent my smarthost; received via SMTP or fetchmail System mail name: localhostIP Address to listen on for incoming SMTP connections: 127.0.0.1 Other destinations for which mail is accepted: <blank>Machines to relay mail to: <blank> Machine handling outgoing mail for this host (smarthost): smtp.gmail.comHide local mail name in outgoing mail ? NO Keep number of DNS queries minimal(Dial-On-Deman) ? NO
 Now configure the password client
$ sudo vim /etc/exim4/passwd.client gmail-smtp.l.google.com:yourAccountName@gmail.com:y0uRpaSsw0RD *.google.com:yourAccountName@gmail.com:y0uRpaSsw0RD smtp.gmail.com:yourAccountName@gmail.com:y0uRpaSsw0RD
 Specify the port,
$ sudo vim /etc/exim4/conf.d/transport/30_exim4-config_remote_smtp_smarthost # add the following line after the line containing 'host_try_auth ..' port=587
 Add your outgoing email address,
$ sudo vim/etc/exim4/email-address # myuser@localhost: firstname.lastname@example.org yourUserName@localhost: yourAccountName@gmail.com
 Update the exim4 config
$ sudo update exim4.conf
 create a ~/.muttrc and add the following,
# mail check options set pop_host="pops://username:email@example.com:995" set pop_last unset pop_delete # mail send options set sendmail="/usr/sbin/exim4" # check for new mail on startup exec fetch-mail
 The necessary configurations are done. Open up a terminal and issue the following command
This will ask you to accept a security certificate and then check your mails. If the configurations are done as given above, you should be able to get the list of mails in your gmail inbox.
If it shows the error “/var/mail/UserName: permission denied (error-13)“, then send a test mail to ‘Username@localhost’. This will create the required /var/mail/UserName and make things work fine.
Happy mutt’ing 🙂
