I'm not sure I fully understand this and what to do about it.
Are you saying that even though I turn "automatic removal" off I will
still have postings from certain list members NOT reaching the list (but
bouncing with an error message back to me, the list owner -possibly also
with an error alert to the poster as well)?
Are there other restrictions in the Mailman software which stops
postings based on other criteria? If yes, can this/these features be
turned off so in the end I only rely on "only allow posting from
existing members"? I assume having the latter enabled will at least
prevent automated spam messages from reaching the list.
Alternatively I'm guessing the solution is to set the list to moderation
and approve every single message manually. I do have a relatively
low-volume list, so this is doable (but not something I would enjoy
enabling) -how is this done actually? By logging into the administration

simpler/quicker by simply pressing reply to a certain admin message or
