At this point, perhaps it is useful to enumerate requirements on the
solutions.
You mentioned two requirements:
(1) letting the sender exclude the reply address (normally From or
Reply-To) from the followup list;
(2) letting the sender include a public recipient while excluding
that recipient from the followup list.
Here are two more requirements:
(3) letting the sender _include_ the reply address in the followup
list---consider non-subscriber messages to mailing lists;
(4) letting the sender specify more than one address for
followups---
consider messages crossposted to two mailing lists.
Aside: I generally find it unhelpful to enumerate "requirements" because
these things have different degrees of importance. There's nothing
wrong with enumerating "goals" or enumerating "problems" to be solved,
but calling them "requirements" makes it seem that they're
non-negotiable and all of equal importance. We'd probably be happy with
a partial solution - one that solved the worst of the problems without
introducing harmful unintended effects -, and we probably won't find a
complete solution anyway.
To-NoReply flunks #1.
Not so, the sender has the option of saying "Reply-To: nobody:;"
