I followed this guide at kernel-panic.it. Below you'll find a small steps-to-follow guide with some additions.

What to build

I've set-up a mailserver that supports multiple domains. It uses:

• Postfix as MTA (with greylisting)
• Postgrey
• MySQL as backend
• Dovecot as IMAP/POP3 server and Local Delivery Agent (LDA)
  • with quota
• Control plane by amavisd for:
  
  • Anti-spam with Spam Assassin
  • Anti-virus with clamav
• Fetchmail to fetch remote email and inject it in your mailserver
• Squirrelmail for webmail.

What to install

At the time of writing I use OpenBSD 4.2. I make use of packages and ports to make this all work.
