Exchange 2003 relaying spam
Posted on 2012-09-05
Hoping someone can help.
I have a client who is running SBS 2003, every some often the server is sending SPAM, but the problem is that I have checked every computer on the network for virus nothing found. I have also checked the server for any open relays and don’t have any.
When I check the queue there are a large number of emails and under the sender it shows email@example.com or “various names@ domain name”.
Any help of hint is greatly appreciated.
