This is another airport where I didn’t have information as of 2017, but it looks like they’ve updated a few things. Thanks to Robert for pointing out information!
From the airport maps, there is a drop box pre-security as soon as you walk into the main area on the Departures level (level 2). Turn right as you enter the door and start looking for the defibrillator and courtesy telephones.
The airport maps page has several PDF maps, including the departures level.
Robert submitted there is a Blue mailbox (possibly a USPS collection box) on the second floor between the Southwest ticket counters and the ticket counters for all other airlines, across from the security checkpoint and the information desk.
Pickup time: 3:30pm every day except Sunday and holidays.
