The kernel matters a lot with NFS. Some kernels are more broken than others. Attribute cache also matters. http://wiki.dovecot.org/NFS > I store mails on NFS, and index on local disk.

If all of it is done on the same server, then pretty much the only thing you can change is the kernel or somehow try to work around its bugs. I can think of only this fix on Dovecot's side: http://dovecot.org/list/dovecot/2006-December/018145.html Hmm. Actually I just realized another reason that could cause these: Are the clocks on the NFS server and on your Dovecot machine synchronized? They must be less than 1 second apart at all times or you'll begin to see problems.
