I tried this a few times as a little kid to see if it would work. If I sent it from my home, it didn't work and I got it returned with red pen notes on it explaining how to send it properly. I am sure it looked like a little kids writing, so they gave me the benefit of the doubt. Next I mailed it from the post office and that actually worked, as long as it was being sent locally.
