Others might disagree, but I don't think that MTA ought to deliver messages to list (or list administration) addresses that don't exist. The MTA should refuse to accept delivery of such messages. I also think that judicious pre-Mailman use of spam filters cuts way down on the amount of junk that Mailman has to process. I've been running one of my lists since 1996 (it has existed since 1989), and the admin addresses for that list gets hundreds of spam attempts every single day. After some tinkering, I've managed to adjust the filters so they keep out almost all the spam while letting through almost all the legitimate requests (I do check manually to make sure that no valid requests get dumped by mistake). Bouncing spam is, ironically enough, one of the best ways to get branded a spammer by certain ISPs. I think we have a duty to at least try to weed out the spam and not have our autoresponders make the problem worse by trying to bounce the stuff. -- Heather Madrone ([EMAIL PROTECTED]) http://www.madrone.com "Everything I never wanted to know I learned from the Internet." -- Morgayn Madrone, age 17 ------------------------------------------------------ Mailman-Users mailing list [email protected] http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
