You Tagged phpmailer so I'm guessing you're using the phpmailer class.

There you just have to

$mail = new PHPMailer(); 
$mail->IsMail(); 
$mail->From = $senderEmail
$mail->ConfirmReadingTo = $confirmEmail
... body etc here ...

if your are not using phpmailer you have to add the "X-Confirm-Reading-To" header to your email.
