In my previous blogs I have documented getting my Linux VPS server and installing WordPress blogging software. Next comes email.
There are really two parts – the sending and receiving of emails at the server level and the reading and sending emails from the desktop client. I will also setup Webmail sometime in the future.
For the server the two most popular *IX MTAs are Sendmail and Postfix , with Sendmail being the standard on Unix servers and Postfix the standard on Linux servers. I choose Postfix as I’ve exclusively used Sendmail in the past and I wanted to see what it was like.
There are two excellent Wiki entries for setting up Postfix , Dovecot and SASL/TLS on Centos.
Setup basic Postfix and Dovecot first ( the only thing extra I had to do was a chown -R user /home/user/Maildir in section 3.3 )
Once the above works then do the SASL/TLS setup
If you have a firewall setup like me then you need to allow ports 993 and 995 for the encrypted versions of imap and pop3.
For Centos 6 use system-config-firewall-tui to easily configure the firewall for IMAP and optionally pop3.
Future things to do are to install a Spam control system and a Webmail application.
