I know how to discard messages automatically. But on most lists the 
default is to hold them. The question is how mailman is used. If the 
list are there for communication only with list members then it's an 
option to discard messages. But if you use a list as an official contact 
you cannot simply discard all messages from nonmembers.

Sometimes people send mails to a list from an alternative address or 
someone not on the list wants to contact the list.  If this is an 
intended use of a list then discard by default is no option.
