The more people running sites who have this information, the better.

Graham Toal, a TISPA member, replaces routine CHECKCOMPAT (which was designed to be local code) in conf.c in sendmail with extensive code. His approach has made Eric Allman's www.sendmail.org page and can be found at <http://www.gtoal.com/spam/sendmail.html>.

Although the code can be tweaked to bounce spam immediately, usually it just tags it with an extra header and allows the user to filter or delete it with procmail or Eudora filters. It implements a scoring system and has been pretty stable for the last month or so with very few modifications being needed to the ruleset any more. (In fact, Tispa members will have been wondering why I've been so quiet on the subject of spam on our mailing list recently - that's why - it's so long since I've had any I don't have much to say on the subject any more :-))

Graham indicates "Anyone else who is not a Tispa member who wishes to use this code must request and be given explicit permission from me."

Which is almost always granted unless your surname happens to be Wallace :-) It's really just a way to make sure I keep a mailing list of everyone using the code so I can notify people of bug fixes. (Of which there's been one so far) I was CC'd this mail; I'm not a member of nanog (though I guess I should be; too many lists, too little time) so if there's any further discussion on this topic that I can help with, I'd appreciate if someone could forward me any articles that need a reply or remember to cc gtoal@vt.com when you post them. Thanks. Thanks G
