I was hopeful too :(

Mail to mailman at mydomain.com should be processed as a post to the
'mailman' list. How it is handled depends on list configuration. There
is a suggested config for the list in Mailman's data/ directory, but I
don't recommend that. In particular, I recommend that the members of the
list and the owners of the list be the mailman site admin(s) and the
following specific settings.

Privacy options... -> Subscription rules
  advertised = No
  subscribe_policy = Require approval
  unsubscribe_policy = No
  private_roster = List admin only
Privacy options... -> Sender filters
  dmarc_moderation_action = Munge From
  dmarc_quarantine_moderation_action = Yes
  generic_nonmember_action = Accept

The reason for accepting messages from nonmembers is this address is
exposed on listinfo and admin overview pages as a "help" address.
