Its getting weirder and weirder. I can ping everything.
I have reconfigured dyndns.org and the servers mailsettings.
Result:
One minute it works the next it dont (so it seems). I can send all the mail i want. sometimes i can recieve mail, but the next minute i'm getting the following message from my backup-MX:
"This is the Postfix program at host fupA.post.tele.dk.
I'm sorry to have to inform you that the message returned
below could not be delivered to one or more destinations.

If you do so, please include this problem report. You can
delete your own text from the message returned below.
The Postfix program
: mail for kongebro.dyndns.org loops back to myself"
I have no clue as to what is wrong. All the settings are the same as on my other server (that works like a charm).
hope you can help me
Best regards
