Shouldn't mailman (or any good mailing list server) be automatically
removing bouncing addresses? I can see that if the old mailing lists
weren't that advanced that you could have 20 years of buildup of bad
addresses, but shouldn't mailman have unsubscribed these addresses after
6 months of bouncing? I know on the several mailing lists I administer
that bad addresses get auto-unsubscribed.

And, if there are that many bad/bouncing addresses on the list in
question, how many honeypots are out there flagging this sender as a bad
sender and harming the listserv, or possibly the whole domain or IP as
being a problem sender?

Definitely. It is important for people who are using email at all
professionally to understand that email delivery is *NOT* instantaneous
despite appearances. And that email delivery regularly takes a few
minutes to an hour, but can, under absolutely normal circumstances, take
3 or 4 days. And that the US Government has legislation that defines
normal email delivery to be within 30 days (yes, a whole month)...
