Forging the "mail-from" address is simple. It doesn't mean 
that the spammer actually used your server. You would need to 
dig a little deeper into the full headers of the message to 
determine if it actually was being sent through your server.

You probably want to find a how-to that tells you how to 
insure that you are not "relaying" spam. I'm sure there are 
many out there, you would just need to find one that is 
particular to your SMTP server.
