one thing to definitely watch in OpenBSD is their new mail daemon, OpenSMTPD. It has a configuration syntax that is about 100x easier to setup and understand than anything else out there, although they are still working to get it up to par feature wise. The code is also written with a heavy focus on security, correctness, and simplicity.
Its definitely something to watch for all those hackers that want an alternative to gmail that isnt the insanity of a postfix/qmail setup.
listen on em0
map aliases { source db "/etc/mail/aliases.db" }
accept for local deliver to mbox
accept for all relay
