Well, there are at least two issues here.  First, you may be
overwriting information given by the user - it is certainly not
unheard of for a user to have a Reply-to address.

Second, you are modifying the expected behavior of the recipient's UA.
I would be very surprised if you haven't already seen messages sent
through your mailing list that were meant to be private.  When it
comes to this area, it's a matter of erring on the side of privacy, or
getting the message out to your list.  The former will cause you grief
because you won't see messages you should have seen; the latter will
cause you grief because you will see a message that you shouldn't
have seen.  I believe the latter is worse because its hard to
embarrass yourself by accidentally NOT sending a message out.

It should be noted that RFC 1123 *did* address this issue.  Now if
only there weren't all those mailers that don't believe in envelopes.
