Reply-To mailing list?

I don't think the point for the change was understood here.

When Mailman is set to assert the Reply-To header to "list", it will invalidate the mail signature by many servers making others regard the email as forged. This was a slip up on this list; other lists on this server as set to not alter the Reply-To header.

It is my opinion, and that of others, that this is best solved by mail clients observing the List-* headers.

Further more, I recommend the use of "reply-all" as a default, because it is possible for a list to receive an email from someone who is not subscribed. With reply-all, your email client shall include both the person and the list, thus eliminating the reply-to issue. It also let's the recipient know they were being addressed in the response (commonly known as "mentioned").
