By far, IMHO, the best is cyrus-imapd ... it was originally developed by 
Carnegie-Mellon University to handle their on campus email, and grew 
quickly out of that ...

If I recall your environment at all, one nice feature of it is that it 
supports something called MURDER, which, effectively, is a way of having 
your mailboxes literally spread out over multiple backend servers ... 
all the mail comes in through ServerA, but, as an example, mailboxes a-m 
get stored on ServerB, and n-z go to ServerC ...

They've also just recently added a replication ability, so that you can 
have backup servers ... ServerD is a backup of ServerB, ServerE is a 
backup of ServerC ...

The thing is, it would most likely eliminate, or greatly reduce, your NFS 
requirements ...
