SMTP server, virus - config changed .... mail bounced

[bjmorse]

Has anyone ever seen this happen before on a WIN 2000 smtp server?
Our smtp server suddenly stopped delivering internet emails to our Exchange server late yesterday. Internal email worked and mail initiated in the Company sent to the internet worked fine. Mail sent from the internet to our Company failed. Bounced.
What we discovered in the smtp config files ... (after talking to Microsoft) the IP address for the 'Forward all mail to smart host' was set, BUT NOT IN brackets!!! [10.10.x.x]
NO - we did not make changes. Have not touched this host in over a year! We did see a virus breakout.
I'm just wondering if there is ANYONE out there that has seen anything like this!
THANKS.

I don't have an smtp server running, just a windows 2000 server with exchange 2000.

Suddenly, since late 25th May, I have not received any mail from outside, and I cannot send mail out to the internet.

No errors in event viewer, email senders get a messages saying the message has been delayed.

Strange!
