So I got new information, because I also posted in the related mailman list. Here is the log, where postfix got the original message (which was sent to 5 mailing lists) and handed over to mailman (which is done 5 times with different postfix ID's). So mailman got 5 times a message to 5 lists, so each member got 5 times the same message. I'm just curious about the message-id=<008b01d10ca4$eb5fd0b0$c21f7210$@de>, this is always the same, but the postfix ID differ. Any glue?
