I have 2-4 servers (usually just 2) accessing mail on a Netapp over NFSv3 via imapd. delivery is via procmail which doesn't touch the dovecot metadata and webmail uses imapd.

The FreeBSD version is the the only major change that I can think of at this point other than the versions of other ports. I'm planning to revert some to 7.x to make sure.
