But then how would I tell mailman to use *that* instance of postfix? What do they mean different classes of mail? If you're using postfix, it should be easy enough to tell it to use a given IP address when transmitting mail to yahoo.com, and use a different address when transmitting to anywhere else. Likewise, if you want to identify different classes of mail and have them sent through different IP addresses, that should also be possible -- so long as you can identify what is meant by different classes of mail. -- Brad Knowles b...@shub-internet.orgIf you like Jazz/RB guitar, check out LinkedIn Profile: my friend bigsbytracks on YouTube at http://tinyurl.com/y8kpxuhttp://preview.tinyurl.com/bigsbytracks -- Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 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://wiki.list.org/x/QIA9

If it's an RFC 3464 compliant DSN with and action of delayed or some heuristically recognized equivalent, it is ignored. The difference between a hard 1.0 bounce and a soft 0.5 bounce was never implemented even though the docs say it works that way. The difference, if it were implemented, would be that failure action with a 4xx or 552 status would count as 0.5 and other failures would count as 1.0, but this is not the way it currently works. All failures count as 1.0 (but only one bounce per day counts). If it isn't, send me a complete, raw copy of the DSN, and I'll fix it and tell you how to fix yours. I'm not working on DSN's, I'm fighting with yahoo over large numbers of stupid, needless 4xx delays in my mail logs (and log reports). There aren't very many things in their generic 'explanations' that seem to apply. So I'm trying to cut down on our system attempting to send mail to 5xx recipients at Yahoo. However, it's only DSNs that Mailman sees, unless your MTA reports a 4xx or 5xx status back to Mailman during Mailman's SMTP with the MTA. In this case, Mailman will log these in smtp-failure and retry the 4xx and 552 statuses at 15 minute intervals for 5 days, and treat the other 5xx statuses as hard bounces.
