The present invention teaches a residential wall penetrating mailbox with enhanced box handling capability, openable by barcode scanning, and openable from either inside or outside a home. A body which is generally column shaped has front and rear doors which open at the top and hinge near the bottom and which have interleaved fingers or members extending from the bottom ends into the interior space of the mailbox. A box tray sits on the interleaved fingers. When either door is opened the fingers of that door lift the box tray upward and out of the box on that side. Thus, a delivery person may access a box from outside the home, while the homeowner may do the same without leaving the safety of the home interior. In addition, an elastic cord and carefully slanted slots on side panels of the front door allow easy retention of a box even further up the front door.
