That explains it.  My mistake in setting up this way.

I'll have to rework my local solution.  Since all mailman
subscriptions are generated from a database maintained elsewhere, I
just need to replace the aliases with new mailing lists that are
supersets.  A bit of work but doable.  Until then, I'll just manually
expand on the Cc to the set of lists covered by an alias to avoid
sending dups.  These lists go to a set of non-technical volunteers so
best not to annoy them.  Volunteers are already hard to come by.
