It’s there on Google Maps; a standard blue drop box. I double checked Google Maps and there are no mail facilities for Terminal 2.
Note: as of this update Terminal 2 is Southwest Airlines and Terminal 1 is every other airline. If you’re flying Southwest it’s probably a three minute walk or so from where you get dropped off to the drop box.
