Postfix

It seems that our mail server was down so I stopped whatever I was doing to try and fix the issue, I had no idea what I was getting into, I had no experience with email servers so I decided to try and see what I could find online and one thing lead to another (I started with Postfix first then Exim4, then back to Postfix.) and I found some good guides on how to install Postfix with MySQL and Dovecot. Now all of our email is working correctly and I gained alot of experience with Postfix, MySQL, Dovecot and even alittle bit of Shorewall.
