Mailman doesn't group bounces, but it does group outgoing mail that isn't VERPed or personalized. Thus, Mailman is sending one message to many recipients in the same domain. The receiving MTA may thus reply with one bounce message for all the undeliverable addressees in that domain. Also, Your outgoing MTA may by sending a single DSN covering all the undeliverable addresses in finds in one message. >Second, one of the errors I got is: > >>>> DATA ><<< 461 Too many unknown users from your host.

You have two problems. First, you have a number of bad addresses in the gawab.com domain on your list and you have to stop trying to send to them. Either unsubscribe them or disable delivery to them - also, maybe set bounce processing so it is more agressive about disabling bouncing users. Second, because of your sending to unknown users at gawab.com, that domain is now blocking all mail from you. You need to contact them about removing the block. >As far as I understand no user would get subscribed if he >has no valid email. Which means all those unknown users are used to be known >at one point of time until something happened. So, what? If subscription to your list requires confirmation, then a user at an address must be capable of receiving mail at that address in order to subscribe in the first place, but such an address can later become invalid. Also, there is no check on admin Mass Subscriptions. You can subscribe any syntactically valid address via mass subscribe without any check that it is actually deliverable. -- Mark Sapiro <[EMAIL PROTECTED]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
