[Mailman-Developers] drop mail from posters who are not subscribed!

[Chuck Mead]

Does anybody have a patch making it possible to simply drop mail sent 
from posters who are not subscribed? I run a pile of lists (none of them 
accept mail from people who are not subscribed) and I get quite tired of 
having to manually deal with spam posts from people who are not 
subscribed to the lists.

Any ideas?
