undeliverable mail
Letters going nowhere
Undeliverable mail is mail that cannot reach its intended recipient—the address doesn't exist, the person has moved without forwarding, or the item is refused.
Postal services return undeliverable mail to the sender when a return address exists; otherwise it goes to a dead letter office for processing or disposal.
