So your issue is that mail sent to Mailman is not delivered to Mailman.
I.e. the non-delivery notice you receive is about the message you sent
to Mailman and mail from Mailman, e.g., confirmations, is delivered.

This is actually not surprising as the
<https://help.ubuntu.com/community/Mailman> document you followed is
totally f****d when it comes to setting up delivery from Postfix to Mailman.

It conflates delivery via aliases with delivery via the unsupported,
3rd-party postfix_to_mailman.py script.

See <https://wiki.list.org/x/15564817>, and decide which delivery method
you want to use, and if you still have issues, we will try to help, but
be aware that we are much happier supporting the standard delivery via
aliases rather than postfix_to_mailman.py.

Also:
1) Please keep this on the list.
2) If you have further DSNs from google regarding delivery to a list,
the actual content of the DSN would be helpful.
