Probably not, but I suggest you add at a minimum

mailman-owner and
mailman-bounces

Monthly password reminders are sent from the mailman list so bounces
will go to mailman-bounces and then notifications will go to
mailman-owner. You might get away without mailman-admin as that is
just a historic synonym for mailman-bounces.

It puzzles me too, but it looks like the MTA that generated it is at
ESC13.midphase.com and is Exim 4.43.

I don't know if this is coming into play here, but Exim can be
configured to automatically recognize Mailman addresses and do the
piping without explicit aliases. If this is the cPanel web host (also
running Mailman) that you refer to, that's likely what's happening
here. There is an Exim configuration document at
http://www.exim.org/howto/mailman21.html which you might look at to
see if there might be a way to let Exim do its Mailman thing in
general and not do it for your lists.
