We get this fairly often with moderated lists; it’s usually because the sender’s mail client grabs the listname-bounces address from their recent addresses cache when they start typing the address in the mail composition dialog.
It would be rarer with unmoderated lists, but anything that would trigger a moderation notice (for things like too many recipients, message too large, etc) will stick that address in their recent addresses list. this is the bounce notice we get when that happens: "The attached message was received as a bounce, but either the bounce format was not recognized, or no member addresses could be extracted from it. This mailing list has been configured to send all unrecognized bounce messages to the list administrator(s)." There wasn’t a copy of your bounce on this posting.

Instead, I the list admin receives a message via the bounces-address with a copy of the attempted posting. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs ------------------------------------------------------ Mailman-Users mailing list -- mailman-users@python.org To unsubscribe send an email to mailman-users-le...@python.org https://mail.python.org/mailman3/lists/mailman-users.python.org/ Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: https://www.mail-archive.com/mailman-users@python.org/ https://mail.python.org/archives/list/mailman-users@python.org/
