We went through a courier to dovecot conversion.

There are a couple of things that might be causing this problem.

1. Dovecot namespaces
2. Client configuration

Your namespaces might not be taking into account the fact that
courier prefixed all files and directories in the maildir with a dot
(.).

You can get around this a couple of ways. We had almost no IMAP
clients under courier, so I renamed everything in our IMAP client
directories away from .files and .directories, and used a default
namespace without dots.

Also some clients like Apple Mail needed an IMAP prefix like INBOX.
to work with courier. I had to remove those with the dovecot
namespace I set up.

Hello,

I am running Dovecot 0.99 on OpenSuse 10.0. Previously, I was running courier IMAP with vpopmail on Suse 9.3. In the process of the
change, I decided to sing MySQL to authenticate the users, provide home dir,
uid and gid.

I tar'ed up the old mail directories, moved them to the new server,
added a new user and group to own the files, set the files uid/gid to match
the values in the db. Next, I followed the Migration directions on http://wiki.dovecot.org/Migration. I can successfully authenticate
the new users, have no errors in the log file but when I am logged in I
only see the Inbox. There should be other folders as well as mail in the
inbox. No errors in the log files.

Any ideas?
