What you really need is Per Recipient Data Response ( http://tools.ietf.org/html/draft-hall-prdr-00 ) but that died in 2007. People use many different awful hacks to achieve this functionality but I would stick for rejecting the message for all of them. Due to the limitation of not have the full recipient list in policy daemon ate OEM stage, a milter would be the best tool to achieve this. José Borges Ferreira
