If you just want to block those outright, look at the features in your MX (sendmail, postfix, etc.) - it verly likely has features to do a reverse lookup of the sender's IP and whitelist/blacklist for domain names from that so you block the sender at SMTP time. Don't get tunnel vision about SpamAssassin being the only tool available for this sort of thing... :) -- John Hardin KA7OHZ http://www.impsec.org/~jhardin/ [email protected] pgpk -a [email protected] key: 0xB8732E79 -- 2D8C 34F4 6411 F507 136C AF76 D822 E6E6 B873 2E79 ----------------------------------------------------------------------- Joseph Goebbels had a Ministry of Truth.
