I don't have the necessary background to set up a mail server and all the attendant pieces all by myself but I've set up a perfectly acceptable mail server (with spam filter, AV etc) numerous times using iRedmail.
Did it on Ubuntu 12.4 (which was the stable release at the time) in a Xen server VM, because why tie up a whole physical server just for email? But now I'm a big fan of ZFS for RAID implementation so if I was doing it again I'd go that way instead (because I never could get ZFS to work under Zen)
It was a just to see if I could do it thing. I don't handle nearly enough email to justify the effort to maintain a mail server. Besides, gmail is amazing at filtering spam.
