I can find no mention of a "Mail-To" header in RFC822. However, RFC822 is
quite clear about the intended uses of "Reply-To", as shown by this excerpt:
4.4.3. Reply-To / Resent-Reply-To
This field provides a general mechanism for indicating any
mailbox(es) to which responses are to be sent. Three typical
uses for this feature can be distinguished. In the first
case, the author(s) may not have regular machine-based mail-
boxes and therefore wish(es) to indicate an alternate machine
address. In the second case, an author may wish additional
persons to be made aware of, or responsible for, replies. A
somewhat different use may be of some help to "text message <-- NB
teleconferencing" groups equipped with automatic distribution
services: include the address of that service in the "Reply-
To" field of all messages submitted to the teleconference;
then participants can "reply" to conference submissions to
guarantee the correct distribution of any submission of their
own.
The *real* problem is that some MTA's do not use the SMTP envelope return
address when sending delivery error messages - the SMTP envelope has
kaffe-approval at kaffe.org as the return address, and it's repeated in
the message as the "Return-Path". This is where error messages should go,
not to the "From" or "Reply-To" addresses.
Mind you, the mailing list software should be smart enough to filter
out error messages.
