Server Banned Members

You can ban certain members or groups of members (i.e., names or domains) from joining or posting to any mailing list on the server. For example, if you are "widget.com" and your competitor is "acme.com", you can ban anyone in the "acme.com" domain from joining. If you receive a complaint from a person that they are being added to your lists without permission, adding them to the Banned Members list can prevent that from happening.
