Abstract
Unwanted electronic messages can be avoided by screening them before they enter a receiving client. Only messages from authorized sending parties are passed to the receiving client while messages from sending parties not previously authorized are discarded or returned. The same arrangement can be used with cellular and conventional telephones, facsimile machines, and other devices.
