RBLs aren't big contributors overall, and are even less important in going after the increment of spam you want to block. The best and more accurate is to look at your maillog and block: 1. IPs and Class Cs that connect to your MX at rates much higher that the largest legit IPs of big ISPs. 2. @sender.domains of received mail that look weird or too numerous to be legit. 3. promote the IPs of DNS and SAV rejects to rejects by IP or Class C. 4. promote IPs numersouly rejected for sending to unknown users to being rejected by IP or Class C (blocking all msgs from them to any of your known users). This kind of tuning will block the sources of spam hitting your IMGate. Len
