What about the Mailman 3 LMTP server?  I plan on backporting this to  
2.2.

The solution in Mailman 3 will be to allow for defining named styles.   
A style is simply a collection of some subset of all the configuration  
variables on a mailing list.  So you could imagine a site that cans a  
few common styles for spam filtering and lets their list admins choose  
which they want.  If they really want to let them have full control,  
they could do that through an 'advanced' tab.
