My personal solution to this issue was to only allow posts to that address 
from the machine itself.  After adding that rule to the Exim configuration 
the amount of Mailman injected spam I have to deal with dropped by at least 
80% percent. 

Here's the ACL rule I use that deals with this case: 

deny   !hosts = +relay_from_hosts
         local_parts = ^[-a-z0-9]*-owner
         message  = unknown user
