I've been running dovecot 1.1 on FreeBSD 7.x for a while with a bare minimum of

doesn't touch the dovecot metadata and webmail uses imapd.  Client connections 
to imapd go to random servers and I don't yet have solid means to keep certain 
users on certain servers.

Are you familiar with:

   http://wiki1.dovecot.org/NFS

Basically, you're running a "try to avoid doing this" configuration, but it 
does discuss some options to improve the situation.  If you can tolerate the performance 
hit, try disabling NFS attribute cache...

Regards,

I am familiar with that page, have taken it into account, worked closly with Timo the author of Dovecot and my mail servers have been running close enough to perfect on 7.x for years. 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.
