So thanks a lot for clarifying. There's only one issue left I'm seeing right now. Mailman does not rewrite the Newsgroups: header. Thus mua's like Thunderbird which also talk NNTP offer to reply to the newsgroup instead of to the list. Arguably this might be called a bug in thunderbird, but I think it would be reasonable if mailman would change "Newsgroups:" to "X-Newsgroups:" to avoid these kinds of pitfalls.
Mailman has a couple of settings in the [nntp] section that control this. See <https://gitlab.com/mailman/mailman/-/blob/master/src/mailman/config/schema.c...>. You can't use rewrite_duplicate_headers to do this because it onle rewrites the duplicates and not the original, but you can use remove_headers to remove the Newsgroups header. If you want to do this you could add
[nntp]
remove_headers:
nntp-posting-host nntp-posting-date x-trace
x-complaints-to xref date-received posted
posting-version relay-version received
newsgroups
to your mailman.cfg to continue to remove the defaults and also remove the Newsgroups header.
