To me it seems like mailman is trying to authenticate as “lists.local” or “mail.local” or “localhost” to postfix (which of course isn’t working), then issues a EHLO/HELO to postfix which is not a FQDN.
If the MTA requires authentication, you need to set smtp_user: and smtp_pass in the 'mta' section of mailman.cfg. By default, these are empty which means Mailman will not attempt to authenticate to the MTA for outgoing smtp. The actual connection to the MTA is via Python's smtplib.
See <https://mailman.readthedocs.io/en/latest/src/mailman/mta/docs/authentication...> and <https://mailman.readthedocs.io/en/latest/src/mailman/mta/docs/connection.htm...>.
