This still breaks the reply-to-author feature.

MUAs will honour the Reply-To header when using the reply-to-all
function: the problem is that Reply-To does not mean what you think it
means.  The header indicates where *you* want to receive replies.  So
the reply-to-all function will reply to *you* (by using the value in
Reply-To), and to everyone else by copying the To and Cc lists.

There is another header, Mail-Followup-To, which tells MUAs to also drop
the To and CC lists.  I know several posters to this very list use it.
However, it needs to be used with care because it can fragment cross-
list discussions and/or prevent non-subscribers from receiving messages.
