It is somewhere between your mail client and Postfix on the Mailman server. It's not Mailman. Are you certain you didn't just send the message twice?
I'm very sure because in the outbox it appears only ones. And I copied the headers again, just to make sure I do not made a mistake the first time. But again no difference with commandline comannd 'diff'. That is very curious :-(
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:
