I'm facing the same problem all of a sudden since this morning. We could send and receive mails without any issues till this morning and all of a sudden i cant receive mails. When I tried sending a mail from my gmail acc to my mailenable acc i got the following message.

Technical details of permanent failure:
DNS Error: Domain name not found

I am using the basic mail enable that comes with Win Server 2003 and Plesk.

I just had the same problem. Suddenly to I was not able to receive mails. ME returned 550. Even on mails send from local services.

In Messaging Manager -> Post Offices -> "postoffice" -> Domains
One of the domains was disabled by accident.

Best Regards
