Hi all - I have a bounce scenario with mailman. It appears that mail can't be delivered to a certain user ([SF:dddd.com/username]) and it's disabling a different user (aaaa at bbbb.com). Here's a snippet: =============================================== This is a Mailman mailing list bounce action notice: List: The_List Member: aaaa at bbbb.com Action: Subscription disabled. Reason: Excessive or fatal bounces. The triggering bounce notice is attached below. Questions? Contact the Mailman site administrator at mailman at bbbb.com ---------- Forwarded message ---------- From: <POSTMASTER at cccc.com> To: <the_list-bounces at bbbb.com> Date: Thu, 22 Jul 2010 12:18:28 -0400 Subject: Message Delivery Failure Message could not be delivered. Error was: The mailbox is not available on this system The following recipient(s) could not be reached: [SF:dddd.com/username] Message contents follow: =============================================== First off - dddd.com/username does not look like a email address to me - could it be a local delivery mechanism? Second, there are list members with the dddd.com address (about 6 of them). They are not being disabled for excessive bounces. Third - why is aaaa at bbbb.com being disable on account of dddd.com/username not being reached?!?! aaaa at bbbb.com is actually a mailman admin and moderator for the mailman service. I just don't get it.
