What I can tell you is Mailman will not interpret a message with a 4xx status as a bounce, and it is the MTA, not Mailman that is responsible for retrying 4xx status returns. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
