This is very difficult to understand. At the very least, Postfix's
Received: headers should include time stamps and queue IDs which would
be different for the two messages.

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

What are the rest of the postfix log messages from 'grep 6D42445B' and
