Hi,
I've got a list with ~1600 subscribers (Mailman 2.1.39). It gets one or two messages posted to it each day (by subscribers).
The problem: subscribers are all receiving duplicate copies of the original post and any replies.
Are you saying that each list member receives 2 copies of an original post addressed only to the list?
All the subscribers are have "nodupes" switched on, and the list is set to replies to go to "This list".
That wouldn't be relevant for an original post addressed only to the list, nor would it be relevant for any user not directly addressed in To: or Cc: of the post.
I restarted the qrunner with: bin/mailmanctl -s restart
That seemed to resolve things for a moment but then it started up again.
Does anyone have any tips or pointers?
Ensure you don't have multiple runners processing the same slice of their queues. See https://wiki.list.org/x/4030715 for the procedure to stop ALL Mailman processes and then start it only once.
Examine the Received: headers of both copies to determine the paths that the message takes from poster to recipient.
