Necro'd this thread because I just did this and this one came top in my search...

Code:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/**
* CodeIgniter 2.1.0
*/

/*
If you send an email using Outlook, there are two optional checkboxes that can be checked:

1.  Request a delivery receipt for this message.
If you check "delivery receipt", the "Return-Receipt-To" header field is added to your email. For example:
Return-Receipt-To: "User name" <[email protected]>
The delivery receipt (i.e. Return-Receipt-To) is a request for the receiving mail server to send a DSN (delivery status notification) as soon as it receives the email.
usage eg. //$this->email->set_header('Return-Receipt-To', $FromName . ' <'.$FromEmail.'>'); //delivered reciept

2.  Request a read receipt for this message.
If you check "read receipt", the "Disposition-Notification-To" header field is added to your email. For example:
Disposition-Notification-To: "User name" <[email protected]>
The read receipt (i.e. Disposition-Notification-To) is a request for the receiving email client to send a DSN as soon as the person opens the email.
usage eg. //$this->email->set_header('Disposition-Notification-To', $FromName . ' <'.$FromEmail.'>'); //read receipt

Note: these are not supported by all email servers or clients.
