You don't get a notice for every bounce. With all the notices enabled as
you posted earlier, you get every message sent to the list-bounces
address which Mailman can't parse as a bounce. Normally, this is only
spam. You also get only one "bounce action notification" containing a
copy of the disabling bounce when Mailman disables delivery to a member
for bouncing, and you get the "unsubscribed" notice when the member is

In this case, you should have received the "bounce action notification"
messages for each of the unsubscribed members three weeks prior to their
being unsubscribed. If you didn't receive these, there is some problem
with their delivery. Maybe they went to a spam folder, maybe your ISP
rejected or discarded them. The outgoing mail logs on the Mailman server
will have more info if you can convince someone to look at them and they
know what to look for and they haven't been rotated out of existence by now.

No. Laura is talking about the IP address of the Mailman server.

No, 2.1.20 is the latest 'stable' version of the 2.1 series. Mailman 3
is a major change and is currently recommended only for new lists as
there is as yet no defined migration path for MM 2.1 lists.
