Ah, this is a good criticism: other MTA's bounce messages can't be trusted to be readable by the sender. Mailman after all, is sending a notice, not exactly generating a bounce. A better policy-server might greylist non-member senders. 95% of the spammers will go away. All of the normal posts would go right through. Members who send from the wrong account would get the usual Mailman notice. Occasionally wrong-account-posters would have to wait a long time on their notice. > Because of the specific issue with Yahoo, he "deeply regrets that we > must make a special exception for Yahoo." > > When implementing that policy exception for Yahoo, it would make sense > to do so at the MTA level, as you suggest, if his MTA provides the > hooks and he can write the needed glue code. (It's a bit much to call > that exercise "configuration", IMO.) Yeah, I just bristle at a hack for one destination based solely on it's size, when this is a general problem. It could be that other ISPs blacklist servers based on the ratio of valid:invalid addresses that you send their way (AOL does this). We just notice Yahoo or AOL because they are big, and our phones start ringing when they blacklist us. This treats a symptom, not the problem. The problem is that we are making net.messes by automatically replying to junk. It would be nice to see a general fix. - H -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) iD4DBQFEB+JFOy/dHTCUq6oRAnonAKCbxFOCNY4UXfHHugXrp8aVKzQRUgCYgcv1 bbAo8RhAMAotNPoHtljqUA== =2gHo -----END PGP SIGNATURE----- ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org 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
