First off, I consider it very bad manners for a side to send non-fatal warnings (i.e. retries) for messages coming from a list. IOW, if the message has "Precedence: bulk" a site should /not/ send a try notification. Most MTAs I believe either suppress these by default, or can be configured to do so. I seem to remember a discussion concerning an Exim configuration variable to control this a while back (perhaps Nigel can elaborate).
Sure.
Exim can send delay warning messages out at configurable intervals - see http://www.exim.org/exim-html-3.20/doc/html/spec_11.html#SEC201
A condition variable also controls what types of messages do get delay warnings sent out. By default this does not send warnings out in response to messages with Precedence: set to bulk, list or junk.
Older versions of exim (I guess pre-3.x - which are prehistoric now) did not have the defaults appropriately set. If you are using a version of exim that old then you should upgrade, or if this is impossible then set delay_warning_condition appropriately - documentation for this (from the 3.2x documentation - but this hasn't changed since its original introduction) is at http://www.exim.org/exim-html-3.20/doc/html/spec_11.html#SEC202
It'd be fairly easy to extend BouncerAPI.py to handle ignorable bounces, so I'll try to add something for 2.1.
That would be good. Is there a way of hacking it now? [return an impossible address for example]
One question: should Mailman support doing an (optional) auto-kvetch back to the site's postmaster?
My evil twin says yes to this... however since those people that have their systems so badly configured that they send bounce messages for list mail also don't respond to postmaster mail - one site that is causing me particular problems in that respect currently I now blacklist completely. Autoresponses in error conditions are a good way of building serious mail loops.
