I have php mailer that works on the server and sends newsletters out to clients.
I wnat it to send me read receipts (I know that some users will select dont send read receipt)and delivery receipts.

I tried this:

$mail_body = ''. $news . '';
    $subject = "My Newsletter";
    $headers  = "From:test@test.com\r\n";
    $headers .= "Content-type: text/html\r\n";
    $to = "Disposition-Notification-To: $email";

    $mail_result = mail($to, $subject, $mail_body, $headers);

It sends the mail but without telling me its delivered.
Does anyone know off hand how I can fix this "Disposition-Notification-To:" section to at least send me a delivery notification.

Thanks
