What makes you think it is Mailman? It does not exist on any of my lists, nor does it exist on the lists I receive from others - including this list. (View this source.) Check you MTA. Maybe that is what is doing it. If Mailman is doing it it is somewhere not mentioned in the documentation and does not do it in all setups.
