Thanks Ben, but I realize my question was not accurate. I am disappointed by having recipients in Cc when I use list-reply on my own messages (match alternates).
Ex: - I am subscribed to a list (with mutt's subscribe command), - I have sent a message to A (not in the list), Cc the list and B, - I want to list-reply my own message, to add some remarks to the list only. In this case the defaults recipients after list-reply are: To: the list Cc: A, B A and B are not supposed to read my remarks, and I sometimes forget to remove them (no need to do it when list-replying other people' messages). I have not found an option to change this behaviour, and can't think of a not-too-dirty macro. I don't know if this is relevant: the list is not a real list with appropriate headers, and most of the people use poorly-designed MUA (no Mail-Followup-To, etc.). -- Gabriel
