== Reply problems with mailing lists ==
TODOIf you get a mail via a mailing list and you reply-to-all, then the author will get two copies of your message if he's subscribed to the list. One directly because he's in his message's From header and one via the mailing list. As a widespread workaround, some mailing lists set the Reply-To header of all messages to the mailing list. If users then use reply-to-author instead of reply-to-all, the author will never get duplicates. However, this has some disadvantages: It breaks the original meaning of reply-to-author and if the author is not subscribed, he will not receive replies to his messages.
