Just don't put anything time sensitive in that mailbox. Years ago as a cast member I mailed my payment for a ticket I had received while picking up my first car from Fort Myers. Long story short it got there late thus I got a letter after my cp was over that my FL happened to have a reciprocal agreement with my home state and my license would be suspended if they didn't receive payment for ticket. I had already paid it but FL hadn't received it yet.
