Sorry I wasn't more clear. Was in a hurry typing and left out details.
Many of my users now are receiving emails from other users inside the company (which of course the original user didn't send). It has their email address listed as the From, but they never sent it. Checking out the logs, the majority of the volume pickup lately seems to be coming from one address in the outside world. This address lists an internal user as the From (how they know this is unknown. Email harvesting programs? I'm new in this area). I blocked out the IP address in the SMTP control access, as well as adding the Verify EHLO and Reverse DNS lookup in the AntiSpam settings.
I was just wondering if there were more steps to take.

What do you mean by "spoof mail"? About 99+% of spammers send E-mail using spoofed return addresses.
