Abstract: A damage resistant mailbox assembly to prevent damage to mailboxes and vehicles, persons or equipment which contact same. The mailbox is supported from an upright support post or structure by one or more expandable and bendable spring units. One end of each spring unit is attached to a plate which is in turn attached to the support post or structure. The other end of each spring unit is attached to the closed end of a standard mailbox enclosure. The device provides for movement of the mailbox when struck by external force, within a 360° radius about an axis substantially parallel to each support spring, with each spring biasing a return to the mailbox structure's original position.
