Please fix your buggy server.
Author (or author's UA per author's configuration) sets Reply-To: good.
List expander sets Reply-To: very bad. RFC 2822 says "When the
"Reply-To:" field is present, it indicates the mailbox(es) to which the
author of the message suggests that replies be sent". N.B. "author",
not anybody or anything else.
Well, life is about flux and change.

I'm not telling you nothing. but with a list system, this isn't a 1 to 1
communications anymore. The "list" concept works on the basis the list
address is an "alias user" mailbox which has reached it's final destination.

1. mailing lists have been around since well before RFC 724 (1977). Note
that RFC 724 also defines the semantics of the Reply-To field as an
author-supplied suggestion for responses and specifically mentions
"text-message teleconferencing", i.e. mailing lists.
2. "alias" and "mailing list" are different. See RFC 2821 section 3.5.1.
char *ReplyToSender()
{
char *to_address = reply_to_address;
if (to_address empty) to_address = from_address;
No and no. Reply-To != Sender. From != Sender.
