Delivery Status Notification & Read Receipt in SMTP

Question

How can I request Delivery Status Notification in SMTP and how can I parse it? I,m using this as

mailmessage.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess;

Mailing is success,but I'm not getting any delivery status.

Can anyone identify the reason ?

By using

message.Headers.Add("Disposition-Notification-To", "emailid");

The read receipt is received, Could I set the content of the read receipt in the original message?

Thanks in advance for any help...!!!

i can do this by adding smtp.DeliveryMethod = SmtpDeliveryMethod.Network; the the code like this :

            mm.Headers.Add("Disposition-Notification-To", smtp_user);
            mm.Headers.Add("Return-Receipt-To", smtp_user);

            SmtpClient smtp = new SmtpClient(smtp_address, smtp_port);
            smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
            smtp.Credentials = new NetworkCredential(smtp_user, smtp_password);
            smtp.EnableSsl = smtp_ssl;

            smtp.Send(mm);
