A mailbox protection system that deflects debris away from striking a mailbox that is attached to a bottom area of a mailbox post to reduce a moment of force on the post. A deflection assembly is held in place utilizing a cantilevered structural mounting assembly. The deflection assembly is physically separated from a proximate mailbox that the deflection assembly is configured to protect. The mailbox protection system minimizes or reduces the moment of a force causes by debris striking the deflection assembly.
