1. mael stuff tu self & see how much get lost
2. Mail something to a fake address. It will come back marked "Return To Sender". See how long it takes. But make sure the address really doesn't exist or it will never come back.
3. Mail to a buddy by placing your friend's address as the return address and your own address as the delivery address. Don't apply any postage or stamps. Throw it in the box. Wait and see if it gets "returned" to your buddy successfully or not. I've always wanted to try this but never done it myself. PS. this may be illegal I have no idea.
