Robert wrote in that he found a blue drop box:
Curbside in front of Terminal A, standard blue mail box
Here’s the location on Google Maps. It’s near the marked “Alternate Entrance” for those with disabilities. There’s also a FedEx drop box close by.
The terminals are connected pre-security so it’s not a long walk to get to the box if you get dropped off at Terminal B.
