The whole reply-to thing came up long ago.  It's been argued again and
again.  Personally, I think email clients can make pretty good guesses
as to what is a list email and what is a personal email and provide the
appropriate "reply to" options.  Email lists shouldn't bother with
munging Reply-To fields, but Mailman is pretty smart about leaving a
Reply-To field alone if it's been used by a list member for a specific
purpose.

Let's say I post an email prompting people to vote for something, and I
set the Reply-To field to something like chewie+vote001 at wookimus.net.
Now my procmail script can pick up replies to that address, as long as
the Reply-To field hasn't been munged by the list server.

Reply-To can be useful, but it should be used intelligently, not as a
crutch for lazy email users.
