Summary: list of allowed addresses under privacy options

Initial Comment:
Under "Privacy options" it would be have more options for banning/
allowing subscribers.  The ban_list is good, but if a list admin is 
looking to restrict membership to a handful of domains, the regular 
expression gets cumbersome (trying to invert certain portions of the 
regular expression).  I implemented a regex example that I found on 
the web and  thought that I had it working, only to check it once 
more and find out that nobody could subscribe. 

One system would be to have an admin configureable setting to 
have either a ban_list or an allow_only_list (maybe even just one 
flag that changes the usage of the ban_list to be more of a ban 
except from list).  That is, if an address is not in the list, ban it.

A more elaborate setup could be something more like the sender 
filters (ie: take one action if the address is specifically allowed to 
subscribe, take another if the address is specifically banned and 
take yet another action if the address falls through both conditions).  
This more elaborate configuration would require more additional 
config entries (??? allow_list, allow_list_action, ban_list_action, 
other_action).
