This is for a source install. While some of it is relevant, your package
also installed a bunch of things in /usr/share/doc/mailman/, in
particular, /usr/share/doc/mailman/README.Debian. Have you read that?

This is for postfix_to_mailman.py. See <https://wiki.list.org/x/15564817>.

I'm a bit confused here. The initial entry above says the message to
mailman at yugi.us was relayed via some service (amavis ?) at[]:10024 which queued the message as DCB473FC72. Then
the next entry processing that queue ID says the message to
mailman at yugi.us is deferred because of a failure looking up
caesar at samsi.us which is the sender. It looks like Postfix is trying to
do some sort of sender verification which fails.

To say more, I'd need to see the output of 'postconf -n', but please
note that this list is not the primary support resource for either
Postfix or the Debian/Ubuntu Mailman package. See
