Hi, I was running ubuntu 11.04 with ISPconfig setup on it (perfectserver). I did a release upgrade from 11.04 to 12.04 and after that I was not able to access my imap (courier) server anymore. I did a upgrade of ISPconfig and was able to access my mailbox again, but now it's empty. I hope it's looking in the wrong directory, but am not sure. Can someone help me troubleshooting? My linux knowledge limited, so all help is welcome. Thanks in advance.
