2821 is about the SMTP side of things.  By the time the MTA is handed
a list of RCPT TO's, it's waaay past time to argue about Reply-to:.
(As a matter of fact, careful reading of 2821 will reveal that there's
no *specific* requirement that the stuff between the DATA and final '.'
even be an 822-style e-mail - I've seen blecherous things that toss an
X.400 blob around in there instead...)

2822 and related would be the right place, as that's about the 822-style
headers on the mail itself.

As already noted by several people, Reply-To: doesn't necessarily impose
the proper semantics (and before anybody pipes up, Bernstein's "Mail-Followup-To:"
isn't perfect either, *and* there's not even an active I-D for it, much less
any sort of RFC).
