<FONT COLOR="#000000">My spam filter (spamassassin w/ bayes + a couple rbls + SARE) is still filtering very well - very few spams get through to my users' Inboxes. However the mail server is working quite a bit harder with all the extra filtering. The 15 minute load average is up from about 0.1 to 0.35.</FONT><BR>

Do you have a firewall that you can employ rbls on? I recently did that here and dropped the workload on our mail server.<BR>
