So what do you recommend then?
We are migrating to Dovecot and we don't have a mail.app application to 
test, so we depended on the users from one domain to let us know something 
is wrong. Since we changed them to Dovecot they could not use folders. They 
could only see the INBOX.

If there is some debugging that we could turn on to send to you? I would 
be more than happy to do it.

Why would future version "break" that setup?
