Do these restrictions apply to all carriers? Ours is a rural route; the carrier delivers in a car. The mailboxes are at the head of the street - one half mile from our house. When there is a package too big to put in the box - and we have the big boxes - the carrier drives down the street, into the driveway, beeping the horn. If we are home, we go out to get the package; otherwise the carrier gets out of the car, and puts the package on our front porch. Is that against the rules?
