SmtpMail.ReadReceipt Property

Sets the read receipt request in the email.

[Visual Basic]
Public Property ReadReceipt As Boolean

[C#]
public bool ReadReceipt {get; set;}

[C++]
public: __property bool get_ReadReceipt();
public: __property void set_ReadReceipt(bool);

[JScript]
public function get ReadReceipt() : bool;
public function set ReadReceipt(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 and delivery receipt:
