Kmail, Evolution, Pine.  Usually specific folder settings.

List-ID does not contain a mailbox; it cannot be used to send to a
mailing list.

I didn't say that.

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.
