With NONE of the above, using three RBLs and our internal rlbdnsd we receive less than one spam per user per week. It's cleaner, faster, far more efficient and requires absolutely no maintenance. I should add that a great deal of spam is blocked with HELO checks. The spam method du jour is to HELO with the recipient's host name or IP (as a string). A cron job adds those to the dns rbl automatically as a backup for when the spammers change tactics. BTW, rbldnsd uses considerably less memory than NTPD. Blocking China and Korea is an extremely effective technique. If we ever get a client in the PRC, I'll be sure to whitelist them -;) BTW, no spam = no viruses. However, we use mime checks to eliminate potentially harmful attachments. ________________________________________________________________________ Total Quality Management - A Commitment to Excellence http://www.TQMcube.com
