That is, the final recipient address after alias processing and forwarding. All mail that is delivered to the same mailbox has the same Delivered-To: address. Postfix local/pipe/virtual delivery agents record the original recipient in the X-Original-To: header. That is, the recipient address before alias processing and forwarding. You can embed the original recipient as an extension to the final recipient address, if you must insist on using the Delivered-To: header.
