[Yum] list policy changes

[seth vidal]

Hi folks,
 I've been on vacation this last couple of weeks and I've noticed
something:

 this mailing list gets 20-50 spam messages a day that get caught by
mailman b/c the messages are not from subscribers. It's good they get
caught but I still get notices about them, etc, etc.

So I'm thinking that I'll just make the default mechanism be discard. So
that if a message is posted to this list by a person who is not a
subscriber then the message will be silently dropped.

thoughts?
