[Mailman-Users] Warning being treated like a bounce

[Paul Tomblin]

I have a user on several of my lists whose ISP (echonyc.com) gets its
email from panix.com, and frequently refuses email from panix.com for
hours at a time, which causes Panix to send me these uselss "could not
send email for 4 hours" warnings, which Mailman treats like a bounce.
When this happens several days in a row, like it often does, she gets
removed from the lists, and she doesn't like that, and neither do I.
Panix refuses to stop sending these warnings, echonyc.com refuses to fix
whatever is broken in their mail servers, and she refuses to change to an
ISP that has a clue.  So I was hoping somebody who knows Python could give
me a hint on how to make the bounce processor not treat these warnings as
bounces.

So far I've figured that the place to make the fix is probably in
Mailman/Bouncers/Postfix.py, and I probably want to key off that "THIS IS
A WARNING ONLY" banner or the Will-Retry-Until header, but I don't know
exactly what to do.  Here's a bounce action notification:

I call these twits pseudo-literate.  That is, they can read but won't.
