To map a post box in OSM you need a latitude and longitude for it.  To
state additionally that it is near a certain address is redundant.
And to tag the post box with the address from the list mentioned above
is probably wrong because this is not the address of the box but some
nearby address.  You need to somehow translate that reference to an
actual location on the globe (lat/lon).

A router just needs to treat post boxes just like any other POI.  You
don't necessarily need an address to be able to route to it.
