local-host-names already had localhost.localdomain listed and /etc/hosts does have localhost.localdomain pointing to 127.0.0.1. Anything else I can try?

And one more item to note, I was notified by all the users that they are being effected by this as well so it is no longer isolated as I was thinking it was.

All seems fine if the incoming e-mail goes to a legit account or if it is spam. It seems that there is an e-mail that keeps getting redelivered to me. I'm not sure where to look at this point.

Any help you can give will be appreciated.

Thanks,
Mel

[till]

The emails to admispconfig@localhost.localdomain are internal messages of ISPConfig to generate statistics.

What is the output of:

ping -c 3 localhost.localdomain

and do you get a smtp prompt when you enter

telnet localhost.localdomain 25

Please post your /etc/hosts file, you can change your real domain, but dont modify the line with localhost.localdomain.
