And how is it configured. As others have said, you need to carefully examine the old configuration and see what changed. If you made a major change in courier-imap version, then you really need to start looking there first, since Postfix tends to be pretty backwards compatible. But in any case, look at the upgrading instructions for BOTH sides of the setup. Good luck!
