Not really. See below.

This says the message was delivered to the outgoing MTA for 3

And this says the post was successfully delivered.

And this says the same Message-ID was automatically discarded 6 seconds
after being sent.

The message is being received, processed and delivered. I am guessing
that at least one of the recipients of the message loops back to
Mailman because one of the list members is a list address or something
is not properly set up with postfix-to-mailman.py. This message is
then discarded by Mailman because of the X-BeenThere: header

You need to look at Postfix's log (/var/log/maillog) to see what was
done with the messages to those 3 recipients.

Also, not to pick on you specifically because you certainly aren't
unique in this, but I wonder why people choose to follow 3rd party
installation instructions about which we know nothing, but come here
for help when they have problems.
