Mails bounced. Help!

[djkoelkast]

Little history:

because of a new gigbit network I got a gigabit network card, it didn't work so I went back to the old card.
Got back to the perfect setup (Debian Sarge + ISPConfig) and changed the /etc/network/interfaces back to how it was in the beginning.

Now all of a sudden all emails get bouced with this message:


This is the Postfix program at host server.***.nl.

I'm sorry to have to inform you that your message could not be be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to <postmaster>

If you do so, please include this problem report. You can delete your own text from the attached returned message.

The Postfix program

<(mailaccount)@server.***.nl> (expanded from <***@***.nl>): mail for server.***.nl loops back to myself


Please help me out on this!

sorry for my panic, after reading and reading again I got this solved.

Don't ask me why but the: server.***.nl was not in /etc/postfix/local-host-names

I assume it wasn't there before, but mail worked before... strange. Now it works again.
