Tell me about it :-( I currently use four levels of filtering: 1. DNSBL lists: blackholes.five-ten-sg.com, bl.spamcop.net, relays.ordb.org (there are others out there, but these seem to have a good impedance match to my personal spam load). 2. Private blacklist of IP ranges that have sent me too much spam. sendmail has a pretty easy mechanism to support this, although it only seems to support /8 /16 or /24 ranges which is a bit coarse. (If you've gotten a "Go away spammer" bounce from me, you were caught by this filter --- let me know and I'll tighten the ranges.) 3. I have noticed that bouncing any machine that sends "HELO sss.pgh.pa.us" gets rid of a ton of spam and viruses. I don't know of any real clean way to do this, but I have a sendmail.cf hack for it. 4. Very long list of procmail filters on header and body patterns. #2 and #4 are fairly personal, in the sense that they have a decent success/failure ratio for the junk mail I get. I wouldn't recommend that someone else try my lists, and in any case they take a heck of a lot of hand maintenance. I've been looking into more automated methods such as CRM114 but haven't made the jump yet. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
