Figured out the problem! The problem is that my backup-mx recieves mail
for *@domains... Ie. it has no user map. After it recieves a mail, it
tries to deliver it to the main server, which tells it that the user
dosn't exist. The backup-mx then sends a DSN via my main server...

So all in all i was debugging the wrong machine :D

I'll find a way to send the user maps to the MX...
