Yes, as explained before: mailman, or the software directly interfacing
with it, translate all message-ids for the newsgroup side.  All headers
are preserved but this one, afaik (Emanual did show me his headers a
couple days ago).

No, still don’t use it, plan to.

Yes it has.  However *your* message is shown as a direct answer to a
fake message my Gnus nowadays create, as a child to this same Bob
Proulx’s message, because the last known message-id of your References
is his, mine is rewritten as containing “mailman” stuff as I said before.

PS: I’m pushing forward the reply-to-all convention so to send messages
to non-existing addresses now x) so to convey the semantics of this
message being adressed to you while being public on that mailing-list
newsgroup. nobody will be bothered by extra mail here anyway.
