A system that determines if mail contains life-harming materials before
the mail enters the interior of a receptacle, i.e., mail box. This
invention accomplishes the foregoing by scanning mail in a control
chamber of a receptacle that is addressed to a recipient which contains
material that may or may not be life-harming; capturing an image of the
face of the mail, which includes the name and physical address of the
recipient and the postal indicia; processing the image on the face of the
mail to identify the mailer and the mail to access the possibility of the
presence of life-harming material in the mail. If certain information in
the image on the face of the mail is known, the mail will be allowed to
enter an inner chamber of the receptacle.
