This seems to solve a non-problem. Unless there are spam messages that where the sender has, for instance, forged the existing "Sender: [EMAIL PROTECTED]" header, signing these messages will add nothing of value. It seems much more likely that a spammer would simply send e-mail to the [EMAIL PROTECTED] list & allow the list itself to propagate it than that they would specifically forge that header.
