Abstract
A filter for restricting access to a user's destination to authorized senders. The filter generates a unique address identification (ID) for each authorized sender. The address ID may be formatted into a unique address by associating with a machine address. The address IDs are stored in a database along with information identifying the sender to which it was issued. The user may revoke a sender's authorization by removing the address ID from the database, or restrict access with policies associated with the address ID.
