If the lists are closed, you could build a tool that would include the
checking mechanism for a local domain. Howver that assumes that people
at your site don't leave forwarding addresses when they leave.

Well it is only perl code, so you could implement just about anything
with enough time/energy.

No. closed only affects how subscriptions are done. It idesn't affect
who can post to the list. The moderator or restrict_post variables are
responsible for that.

No, your not going about it all wrong. Heirarchical lists are
something that majordomo doesn't address currently. I have done some
thinking about it and a suggested scheme was posted to
majordomo-workers a while ago. But it doesn't work in general since it
counts on having comments in the list file when it processes it.
Just out of curiosity, what is the worst that could happen if somebody
doesn't follow directions and subscribes to 2 or 3 of the 3
heirarchical lists. Just a bit more email traffic? Then end of the
Solving the particular problem of multiple subscribes seems to be a
lot of work for little gain. Sending the multiply subscribed person a
nice form message with the output of "which" at the end should
straighten them out I would think.
