In Mailman 2.1.10, there is a new sibling lists feature that can be
used to reduce or eliminate duplicates sent to members of multiple
cross-posted lists.

You can for example put listb at example.com in the regular_exclude_lists
attribute of lista at example.com. Then, if a post addresses both
lista at example.com and listb at example.com, those addresses which are
regular members of both lista at example.com and listb at example.com with
delivery enabled will not be sent the post from lista at example.com.

The rest of Brad's reply is right on.
