anti-spam measure for visad-list and vis5d-list

This morning we had a couple of spam advertisements on the
VisAD mailing list.  So we have now changed these lists to
only accept posts from addresses subscribed to the lists.

This will affect at least some people, who are members of
to visad-list indirectly through other lists, such as
visad@xxxxxxxxxxxxxxxxx  In order to post to
visad-list@xxxxxxxxxxxxx they will now need to join
directly.  Sorry for the inconvenience.

Cheers,
Bill
