ABSTRACT:
A mailbox or receptacle for mail, newspapers, and the like, has two compartments: an unsecured upper compartment and a secure, locked lower compartment, with a partition between the two compartments. A door in the partition allows access to a chute extending downwardly from the upper into the lower compartment. The chute is set at angles which allow mail and papers to pass from the upper to the lower compartment, but prohibits arms or hands from extending into the lower compartment.
