I think the problem is that a given mailman list doesn't have any
concept that there might be other lists in the same mailman instance.
The only way it does what you describe is, essentially, by looking at
the 'CC' in the message and dropping any of those addresses from the
list of addresses it eventually sends to.
Sending to multiple lists, the message is split off at the MTA level;
mailman gets one copy of the message to each of its aliases for the
lists (or however your setup is done).

Sorry if I gave the impression otherwise, but I am not authoritative.
Someone else may know better than I, or someone else may decide that
this is the best thing since sliced bread and is working on a patch
for it right now..
