Mailman could discard most of the spam automatically if it would implement a challenge/response for all messages hold for moderator approval: Mail the sender (usually forged) and ask them to confirm the message (by mail or www). If the message isn't confirmed after 24h, drop it silently and don't bother the admin. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=350103&aid=849711&group_id=103
