Has IPSwitch said anything about releasing patch or update for this NUL address sender 
problem?  Having an "only moderator can post" list that accepts and posts messages 
from anyone sending from a NUL address is a MAJOR SECURITY HOLE!  Also can a NUL 
sender also post to "only subscribers can post" lists?  (I would assume so if a NUL 
sender can post on "moderator only" lists.)
