Put listB at mydomain.org and listC at mydomain.org in listA's
regular_exclude_lists and listC at mydomain.org listB's

A post to all three lists will be sent to members of listC only from
listC, to members of listB who aren't members of listC only from listB
and to members of only listA from listA.

Posts to just two of the three lists work similarly.
