PS: As somebody mentioned, if I hit "Reply" in KMail, I would have your address only, in the "To:" field. If I hit "Reply to all", then I get your address, followed by the list address. This Linux-only mailer gives what you would call wrong behaviour by default. Or, at least it does when responding to certain types of mail-list handlers. With some others, when I hit "Reply", I'm replying to the list.
That latter behaviour is what gnus would call "Broken Reply To". Put very briefly the problem with setting Reply-To: to point to a mailing list is that it makes it much harder to respond privately to a poster. Whereas if Reply-To does not point to the list, it is simple to reply to either the list or the individual poster.
