This property sets the Read Receipt request in the email.
Data Type: Bool
If the value is true, a read receipt request will be added to the email message.
Read Receipt
Some e-mail applications, such as Microsoft Office Outlook, employ a read-receipt tracking mechanism. A sender selects the receipt request option prior to sending the message. Upon opening the email, each recipient has the option of notifying the sender that the message was opened and read.
The following example codes demonstrate how to request read receipt:
