I'd like to propose a little something we'd all love to see. We've seen myriads of tutorials about apache and traditional setups - but hey, what about flexible setup of your own mailserver with virtual mailboxes inside MySQL/mariadb with secure SMTP and IMAP, great RoundCube interface and all running on nginx, not that stinky Apache? I'm sure this would be hot as hell! On the whole internet, there is not a single complete and up-to-date tutorial on this kind of setup. Everything is for Debian 6 and with wheezy released, we all get our hopes up! If you like my suggestion, do comment, guys, and maybe our show-runner Falko and the great team of HowToForge will surprise us.
