I tried both "C-c C-l" and "M-x message-to-list-only" on several
messages, but it does not seem to have any effect. I don't see any
error reports, but nothing happens.

According to http://www.gnus.org/manual/big-message.html , Emacs Message
mode processes the "Mail-Followup-To" header, which seems to be a rarity
these days. "List-Post" et al apparently don't factor into it.
