However errors that occur during SMTP from Mailman to the outgoing MTA are returned to Mailman. Mailman sees the SMTP status return and if it is a 5xx status, scores that as a bounce and if it is a 4xx status retries sending the message to the failed recipient(s) at configurable intervals for a configurable time. The retry interval is DELIVERY_RETRY_WAIT with a default of one hour, but in MM 2.1.23, DELIVERY_RETRY_WAIT is ignored and the interval is 15 minutes. The duration of retries is DELIVERY_RETRY_PERIOD with a default of 5 days, after which Mailman gives up without scoring a bounce. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
