The airport information for the post office wasn’t where I would normally expect it. Instead, it is under “Departure Services“.
The page notes the following:
A Post office is located in the arrival porch open 24 hours. Post boxes are located in the Transit area.
Unfortunately the airport maps don’t seem to work. Google Maps didn’t have much to offer either. Fortunately it seems that this airport isn’t terribly large, but I could be wrong here.
