I'm using ZFS on FreeBSD 8.2. But to be honest, this is a 
personal/private mail-system with limited mailboxes. I really like the 
snapshots in ZFS. Every night I make a snapshot which I send to another 
server for backup. Every hour I make a new snapshot from which I send 
the incremental to the backup-server. That way if the worst happens I 
will only loose 1 hour of mail.

ZFS was built for data integrity, not speed so if it's speed you are 
looking for this might not be the fastest but maybe fast enough.
