This ist the time I sent that e-mail to 5 lists (the announcement that the Mailman server is up and running and for future use) and it seems to me, that it was sent 2 times to each list, wasn't it?
Yes, but if the post was sent twice to each list, the Received: headers of the two posts you received must differ in detail.
Anyway, look at the MTA log and see if there were two deliveries of the post to each Mailman list at around 22:17.
