Status: Closed Resolution: Invalid Priority: 5 Submitted By: Bruce Scherzinger (bascherz) Assigned to: Nobody/Anonymous (nobody) Summary: Mailman Auto-unsubscribes Bad Addresses?
Initial Comment:
I haven't seen any settings for this, and I can only
describe it based on the information that I have. But
today I received bounce notices identically
timestamped for three separate email addresses in the
same domain. The notices all indicated the addresses
had been unsubscribed from a specific Mailman list. I
don't know what initiated the action, and these same
addresses are still subscribed to other, less-
frequently used lists.
I sent emails directly to the three addresses to
notify them of the issue, and I got back a response
from their email server as follows (actual email
addresses omitted or replaced for privacy reasons):

Message: Logged In: YES user_id=1123998 I am closing this because mailman is doing what it should. The users were unsubscribed by bounce processing. The settings for this are list by list on the Bounce processing page of the admin web interface. Mailman registers the bounce notices that it receives in response to post deliveries and handles them according to bounce settings. The remote server has no direct involvement with the unsubscribe. It just returns a notice to mailman just like the notice returned to you when you mailed these addresses directly. The process is described on the Bounce processing page. And yes, bounce notifications can be spoofed, but with normal default settings, the spoofer would have to send 5 spoofed notices on different days, and then the member would have list delivery disabled and be sent a warning, and be sent two more warnings at one week intervals before being unsubscribed. Also, you can select the option to notify the list owner when the subscription is disabled, so unsubscribing a user by spoofing bounces is not likely to be successful if the user actually has any interest in the list. ---------------------------------------------------------------------- Comment By: Bruce Scherzinger (bascherz) Date: 2006-02-23 10:10 Message: Logged In: YES user_id=1415850 I failed to mention that the webhosting company has Mailman v2.1.6 installed. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100103&aid=1437581&group_id=103
