[Mailman-Users] 1 email for multiple email-list recipients on same server?

I don't believe it's a user-education-oriented problem; I want my users to 
do this.

Mailman has the capability via ("Avoid duplicate copies of messages?") to 
determine when email is being sent to an external user that's on its 
subscription list; why not use the same/similar mechanism to check the 
duplications on other subscription lists?

This leads me to believe that this capability is well within the capability 
of Mailman to support.  Alas, I don't have intimate knowledge of the 
internals, and therefore I speak from a very ignorant position.

Also, if the Mailman development community does not want to support this 
feature based upon some policy or principal, I suppose there's little that 
can be done.  FWIW, I think this would be a useful feature for Mailman, but 
that's just my perspective.
