In this how to I will explain how to setup a Postfix virtual mailserver with Courier-IMAP, Maildrop and Postfix Admin GUI. We will secure our mailserver with Mailscanner and Clamav as anti-virus and Spamassassin as anti-spam.
– Installation of all software
– Configuration of mail server it self
– Configuration of anti-spam and anti-virus
I have written this tutorial, because it was very difficult to find a decent “how-to” on how to configure a mail server on a Linux distribution like CentOS.
I have written this tutorial for CentOS 4.4 X86_64, but I should work on all CentOS 4.4 distributions (i386, …) and Redhat-like clones.
First of all, it was a long painful road to walk, because as you all should know. CentOS is not the most progressive distribution, but never the less a very secure and stable one.
