Additionally there are several Anti-spam laws in the works that would
*require* a confirmation before adding a user to a mailing list -
additionally they require accurate unsubscribe information to be
included within each list message.

Mailman meets the requirements of any current laws, and those being
considered by parliaments the world over.
