I think in that case rmail replies only to emacs-devel@, which means
Eli has to add back the other recipients. Eli, do we need a "reply to
'From+To+CC+Reply-To'" feature in rmail? ("wide reply" in Gnus parlance).

Yes, that matches the Mailman documentation. Iʼm not sure what a good
solution is; Mailman adding a Reply-To with both the sender and
emacs-devel would no doubt also break either Outlook or rmail or
both. Not adding a Reply-To at all means the sender would get dropped
<sigh>.
