You are mistaken on both points: the URL above is a rant page
specifically about the non-standard "mail-followup-to" field. And I
have not sent Bernstein copies of mailing list mail, as you could easily
have determined from the mailing list copy; the message was sent *to*
Bernstein with a *copy* to the list. And that is exactly what would be
expected from a response to a message (his) which contained no Reply-To
field indicating that responses should go anywhere but to him (with
reply-all copying the list). As specified for the semantics of Reply-To
and responses in RFC 724 [sect II.C.. paragraph 3)], RFC 733 [IV.A.2.c],
RFC 822 [4.4.3], RFC 2822 [3.6.2], and RFC 3834 [sections 3.1.2 and 4].
None of which mention "Mail-Followup-To".
I couldn't have possibly come up with a better illustration of my point.
