如何使用PHPMailer发送送货回执

I am using PHPMailer to send emails and i want to be able to send Delivery Receipts to the sender

I have tried:

$email->ConfirmReadingTo = "sender@domain.com";

which sends a Read Reciept to the sender

i have tried using the below code to send a Delivery Receipt but it doesn't work - i think it is meant for sending *Read Receipts *

Disposition-Notification-To:

but this is sending a Read Receipt and not a Delivery Receipt

how can i also send Delivery Receipts using PHPMailer?
