v1.0 doesn't flush NFS caches, which can cause this if multiple servers
access the same maildir at about the same time.
http://wiki.dovecot.org/NFS has some explanations of this. v1.1 has
mail_nfs_storage=yes (and mail_nfs_index=yes) which make this possible.
Anyway best would be if you could just redirect the user to the same NFS
server always, even with v1.1 it should give better performance.
