You could be right about warm, moist air leaking in. I am surprised it would be enough to condense on the walls. Do you live someplace very warm and humid in the summer time? I would start by removing the fan and trying to see why it doesn't fit better, adding caulking or even the foam sealing strips you press in. You might also try a flapper over the vent like on dryer vents to keep air from coming in the vent.
