Returned Email

Windows 2000 server running exchange 5.5
Clients running windows xp pro and outlook 2000

I have a few users who keep getting undeliverable email messages. The message says that the address that they are sending it to is not a valid email address. The problem lies in the fact that these users did not send the original email and I am puzzled as to what to do to verify that we are not hacked. I have relay disabled.
Where else to look?

Hi

Could it be a mass-mailing worm/virus problem? Sounds like it. What's your antivirus setup like, and have you got exchange aware av?

Scan the offending clients, and update or install an exchange-aware av solution and scan the mailboxes etc, listed partners here:

We have antivirus software on the server. infact we have two layers.
We have it filters and scanned before it comes into our server and then we use a local scan on all incoming/outgoing email.
However, I am not 100% sure about the client machine.
I will push the virus software to them and see if that fixes it.
