This is a somewhat controversial issue. I've been considering writing
a patch for ezmlm+idx to change this behavior. However, I'm going to
try to explain why it *is* done the way it is; there are some good
reasons.

IP addresses aren't at issue; the smtp-envelope would normally have an
fqdn. And it's quite important that it *never* be an unresolvable
fqdn (fake) or a private-network ip address: the smtp-envelope from
address is the address that bounce messages are returned to. So if it
isn't a reachable address, you'll never get your bounces.
ezmlm isn't the only mailing list system to make this choice; it seems
that majordomo and list-serv also pay considerable attention to the
envelope sender.
Furthermore, the from: and reply-to: headers are, statistically,
fairly likely to have been configured wrong by the user.
