[Mailman-Users] Suggestion: do not include List-Id header on subscribe/unsubscribe messages

[Rich Kulawiec]

Reasoning: those messages are not actually mailing list traffic.  Yes,
they're related to the list, and they're about the list, but they're not
being sent through the list per se.

In addition, one of the things that I've noticed is that filtering/filing
based on List-Id (say, a procmail recipe) will filter/file these messages
along with ordinary list traffic.  But I don't think that's desirable
behavior; especially in case of unsubscribe notifications generated on
the server side (say, due to an excess number of undeliverable messages).

Opinions, comments?
