What are the rest of the postfix log messages from 'grep 6D42445B' and 'grep 4ACCAD07' of the log file?
and here it comes...
for grep 6D42445B:

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

and for grep 4ACCAD07:
Mar 18 22:16:46 hostname postfix/smtpd[9815]: 4ACCAD07: client=localhost[::1] Mar 18 22:16:46 hostname postfix/cleanup[9818]: 4ACCAD07: message-id=5509EB1C.8050605@stoecker-family.de
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.
