OK. This message was received from something on localhost (IPv6 [::1] at
22:16:43 and delivered to all the Mailman list recipients.

And then 3 seconds later something on the same host delivered a second
copy to Postfix which delivered that to the lists also.

So this duplication occurred before Mailman and even before Postfix
delivering to Mailman. It could be anything. You could try grepping the
log for the Message-ID and see if that gives a clue.

Look for an original arrival being passed to some process that returns
two copies.
