I've been working with postfix and stuff earlier, but postfix has the negative point of insane configuration, etc.. Although I got it working in older projects, I don't want to use it anymore.

I'm looking for the lightest and easiest linux mailserver software allowing me:

  • multiple virtual domains and users via database
  • IMAP
  • transport layer security, preferably with PFS
  • spam filter and anti-virus
  • easily letting me combine with or better, has already integrated, SMTP (also with secure layer)
  • quota is nice to have but not a must-have
  • The best I haveever come up with is a good set of instructions. It includes postfix, which I would also like to avoid, but it has instruction and I got it working. [instructions][1] [1]: lelutin.ca/posts/installing_postfix_-clamav-spamassassin-dovecot-_postfixadmin_on_debian_squeeze/
