Yet, there are many people who still think that reply-to munging is
a good thing. Interestingly enough, someone tried to counter the above page by
writing a
Reply-To
Munging Considered Useful (local copy

But the arguments in that page very easily refutable, as I wrote in the
following post when participating to a thread on
the mailman lists.
And better, the IETF has clarified the situation as far back as 2001 in their newer standard on Emails, RFC 2822, which states "When the "Reply-To:" field is present, it indicates the mailbox(es) to which the author of the message suggests that replies be sent." (notice author, and not list software). See the "Reply-To" Munging Still Considered Harmful. Really page (local copy here)
