I'm completely stumped by this problem and I've tried everything at present - including installing dovecot from scratch.

The problem is that when trying to get email from the server -AND- there's email in the account, the pop3 or imap process freezes and no email is fetched. The crazy thing is, that it has been working perfectly, but suddenly I'm getting these freezes both when using telnet from localhost, roundcubemail on the same server and Seamonkey from another computer.

Logging seems to work perfectly. For an account without email, dovecot finds the maildir++ and acts correctly. For an account -with- email, dovecot seems to find the maildir++, but also seems to try Namespace of which I haven't defined any.

I've tried to get rawlog to work also, but that didn't work - the telnet process froze on login even though I'm quite sure I did the right thing and ps showed an active rawlog process

Postfix is delivering the email straight into the mailboxes.
