We reprogram majordomo to recognize that the message had "To: joelh@gnu" in the header and not send it to me when it expands hackers. Sure, sendmail has already sent a message to me, but we keep majordomo from sending it instead of trying to keep sendmail from sending it. Remind me, why does majordomo expand the aliases itself instead of letting sendmail do it with a :include: that majordomo can maintain?
