My favorite SMTP server is Postfix. I’ve been using it for over five years and its never let me down. I’ve used it on Gentoo and Debian, and still do today.

I setup the following features:

  • UCE Controls
  • SASL Authentication
  • Virtual domains and mailboxes
  • Maildrop transport for Spamsasssin integration
  • Backup MX servers as relays

All in all, its awesome!
