yes, but what is mapped here should be collection for outgoing post.  Incoming post, whether individual boxes, should not appear on the renderer as they are not for general use, so the icon/amenity is wrong.  and likely should only be mapped if not near the address node (say, far away from the main entrance).
If there is an outgoing post slot, is it available for anyone and everyone to use, or intended only for residents?
