[Dovecot] Still issues with new message count...

I am still having issues with new message count. When I move a message to another folder, it counts that message as new until you go into that folder. Is there a way I can solve this? Could it have something to do with NFS? I have tried all the NF workarounds with no luck... I have also tried NFSv3 and NFSv4, no difference. I store the indexes on the local drive...
