I would doubt the persons word about getting the envelope back from the Royal Mail. Once it goes in a postbox it belongs to the Crown until it arrives at the address on the front. Strictly speaking mail should be put through the letter box not handed to the addressee outside the property.Obviously if it will not go through the letterbox it could be handed over if the recipient is inside the house. I think who ever told the tale is telling porkies.
