I noticed that this guy's using our domain name as the argument to the HELO command 
during the SMTP transaction. So if the address he's spamming is [EMAIL PROTECTED], his 
ratware used "HELO example.com". None of our servers use just our domain name (they 
all use their fully qualified hostnames), so I added a custom rule which looked for 
"helo=example.com" in the Received: header and scored it at 200 points to overcome his 
using a whitelisted From: address (we've whitelisted [EMAIL PROTECTED]). Works like a 
charm.
