If the above doesn't answer the question, please be more specific about exactly what messages you are concerned about. If you are talking about "unrecognized bounce" notices, these are from spam sent to the listname-bounces address. You can stop them by setting bounce_unrecognized_goes_to_list_owner to No. The risk of a legitimate bounce from a member not being recognized is extremely small. > It would be nice if Mailman could tell the MTA as it was receiving the > message that it wasn't acceptable so it could be rejected then, but > since it generally can't, you need to discard spam, not reject it.
