I've happily been running a mail server on my home network to handle my personal domain email for the last 6 years. The old PIII server that is my mail server is now on it's last legs and I'm contemplating my options.
While I've quite enjoyed the learning experience of getting sendmail and spamassassin running, I'm currently tempted by the 'turkish delight' offerings of google apps.
Before getting completely suckered into the flashing lights of google apps with all their fancy imap, and webmail access, and their superduper spam filter, I thought I'd check with the smart folks here at super user if there still any benefits to running a mail server at home?
Additional info: * Lets ignore the Privacy concerns related with having google host the email. There are plenty of other threads covering this and I'll consider that in due course (if it turns out that from a technical perspective google apps is worth considering). * If I were to setup a new mail server, I'd probably go with Ubuntu, Dovecot and postfix running on some relatively old (but not ancient) hardware.
