I just installed OpenXchange exactly as said in


I could create the oxadmin, an testuser and accessing the web-based interface worked with both of these users. But when I now log on, I cannot access the mailserver. The error message it says in web-access is:

Error: Connection was refused or timed out while attempting to connect to remote server for user michael2 (MSG-1016, -743005457-151

I of course have the open-xchange.log.0, but as it does not only have 5 lines, I just posted this error. If necessary, I will add the log of course, but perhaps this is easy to solve.
