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.  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...
