The address used by the mail transport service is provided separately, through an envelope SMTP "RCPT TO" command. Before final delivery, handling can entail a sequence of addresses that lead to the recipient. It can be helpful for a message to have a common way to record each delivery in such a sequence, and to include each address used for that recipient. This specification defines a header field for this information.}, }
