This is not the message to Mailman. It is some kind of notice being
sent from Mailman to someone (the Message-ID is a Mailman generated
message id). It may be a reject notice to a poster or a notice of some
kind to the list owner or completely unrelated to the 'missing' post.

All of which is consistent with a rejected post.

The message to 1 recipient was not the post. As I said above, it was a
mailman generated notice, possibly about the post. Find this message
in your MTA logs and see who it was delivered to for clues. If it is a
rejected post, there won't be anything else in Mailman's logs.

My best guess is the post was rejected for some reason and the message
to 1 recipient was the rejection notice.

It seems unlikely that the rejection is related to the address to which
the message was sent.
