So "some_site" in your example are all the mail servers around the world
which REFUSE to receive the posting(s) from my mailing list, and thus
sends an error message back to my list server's Mailman software.
And as these error messages on my list-server start piling up from
various mail servers around the world (i.e. "some_site") Mailman says
"OK, enough! The LIST-MEMBER sending those messages has to be banned as
messages from him won't receive a vast majority of the other list
members anyway, so I'll remove him so it won't happen again".
Have I more or less understood it correctly?

OK, I'll ask the server-admin/owner about the logs as I'm not sure where
they are or how to access them. Which logs specifically are we looking
for as I'm sure there are many?
I assumed I would get an error message (email) for every time a posting
didn't reach the list but the latest "bounce action notification" I have
is from 5 months back, so apparently not. Maybe I've messed with some
settings in the Mailman web control panel as I kept getting so many of
them and didn't know what to do about it all.

Again, this is the IP address of certain LIST-MEMBERS, right, and not my
Does this also mean that the same receiving mail-servers will refuse
email sent from the same LIST-MEMBER, but sent directly (i.e. outside of
my mailing list)?

I don't have the capacity nor time to contact every single email
provider refusing to receive messages from certain list members.

Ouch! So it won't accept the email because my list-server PASSES ON a
message, and that IP address is obviously not the same as that of the
LIST MEMBER posting that message in the first place?

I'll contact my server-owner/admin to upgrade the Mailman software.
I see from the Mailman site (http://www.list.org/) that version 2.1.20
is the latest version, and there's version 3.01 as well ("Show don't
tell", whatever that means).
Is 2.18 the latest stable version?

I know many list-owners prefer to have messages reply back to the poster
of the message instead of the list itself (I've read those discussions
many times though I forget why), but for my list I'm sure this would
mean A LOT of list discussions done outside of the list, which in turn
defeats the purpose of my list (sharing information).

Certainly more than a couple of days ago! Thanks for explaining :-)
