Thank you for your feedback. I'm most inclined to handle replies based
on the needs of the particular list. Personally I find myself sending
most replies to the list address and for small lists like the ones I
run, I think that's the best choice. So I'm inclined to add/replace
the reply to header to the list address. I know many high traffic
lists prefer the reply to default directly to the sender. In that case,
if there is an existing reply-to, I would keep that, otherwise, copy the
original from header into the reply-to.
I run a mail client (thunderbird) which recognizes mailing lists, and so
provides me with a reply and a reply-list button. My sense is that
there are alot of mail clients that don't do that, so the default has to
take that into consideration. I think the defaults should provide the
best support for non-technical/inexperienced users. Yahoo, by default
adds a reply-to header.

Ok, I will consider that, though if I really get mailbox names that
long, maybe they should be treated as spam anyway.
