We recently installed Mailman 3 to replace an existing Mailman 2 installation with a large number of lists and users. I'm now seeing a number of users on specific lists whose posts result in:
May 18 14:25:41 2021 (112570) DISCARD: <by5pr09mb52987327de1aa2c199dc4dc1d4...@by5pr09mb5298.example.org>; ['The message has no valid senders'] The post have sender addresses, which are members or owners of the lists, and as far as I can tell, the users are valid. Can anyone shed any light on why a post wouldn't have a valid sender? Tommy M.
