We are currently running dovecot-1.0.10 on Solaris 10 x86.

Several users has noticed that they get different emails when using pop 
vs using IMAP. When I check a user's home directory, I find the 
following situation:

/nfs/mail/1/1/hiro.11/mail/:

I suspect that is less than ideal. What exactly is creating these 
folders, and how do we stop it? I can clean it up ok (which I'd rather 
do as one maintenance) but only once I know it wont happen again.

Should also mention that we have a mbox convert script running for a 
couple of months, to convert their old mail. Then it will be removed:

convert_mail = 
mbox:/export/mbox/migrate/%u:INBOX=/export/mbox/migrate/%u/%u:INDEX=Maildir:%h/mail/

Should also mention, one server in the cluster was incorrectly running 
version dovecot-1.0.2 (boy was that fun to track down).
