To clarify:

The address listname-admin at domain.com doesn't go to a human in Mailman
2.1.x. It is a synonym for listname-bounces at domain.com. The generic
address to reach the owners (admins/moderators) is
listname-owner at domain.com.

I don't think Jim was saying that address (listname-owner at domain.com)
should not be a list member. It shouldn't, but I think what Jim was
saying is that the actual admin/owner email address(es) - i.e. the
ones that appear on the bottom of the listinfo page as

XYZ list run by jdoe at example.com

should not be list members (or at least not unmoderated members)
because otherwise you are advertising an address that can be spoofed
to post to the list.
