a strongbox having an open top and a close lid, the strongbox is adapted to a delivery person to place one or more delivered packages into the strongbox through the open top and the close lid;

a first shutter coupling the strongbox to the outside of an exterior door via the first shutter;

a second shutter coupling the strongbox to the outside of the exterior door via the second shutter; and

a latching mechanism engaging the close lid thereby securing the one or more delivered packages inside of the strongbox; and,

wherein the first shutter and the second shutter each include a shutter standoff with a first standoff end coupled to a respective shutter and a second standoff end coupled to a spring;

wherein the shutters are adapted to slide laterally within a shutter slot passing through the strongbox; and,

wherein a movement of the first and the second shutters causes the shutter standoffs to pivot a pair of hooks on the latching mechanism, thereby disengaging the hooks from a pair of latch catches disposed on a rear underside of the close lid, thereby allowing the close lid to be opened.
