More likely, what is happening is there is a list member whose mail is sent directly or indirectly (after a forward of some kind) to the server at tempest.organization.org. This mail is undeliverable by that server so it is sending some kind of DSN indicating the delivery problem back to the list-bounces address <[EMAIL PROTECTED]> which is exactly what it is supposed to do. Mailman is unable to determine the bouncing address from the DSN which is not surprising if it consists only of the four headers you quoted with no other information in a body or attachment, so Mailman forwards the unrecognized bounce to you. Now it is clear from the bounce log that the message contained at least a Message-Id: header in addition to the four quoted headers. What else is in that message that your MUA is not showing to you? Can you view the raw message source? If your MUA is the same Apple Mail you sent this post with, open the message and select Message -> Raw Source from the View menu and see if that gives you more information. >Any ideas on how to I might proceed to figure out why I'm getting this >bounce, and therefore maybe figure out how to prevent it? You prevent it by removing the offending address from the list. If the above doesn't help find the address, you need to temporarily at least set VERP_DELIVERY_INTERVAL = 1 in mm_cfg.py and then restart Mailman. This will cause each message to be sent individually to each user with envelope from <[EMAIL PROTECTED]> where [EMAIL PROTECTED] is the member address. Then, when it bounces, both Mailman and you will know what address is bouncing. Note that if you have one and only one list member whose address is in the organization.org domain, you could try temporarily disabling delivery to that member, and if that stops the notices, you've found the undeliverable address. -- Mark Sapiro <[EMAIL PROTECTED]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
