PEAR::Mail with DSN SMTP service - php

Question

Do you know if it is posible to set a DSN communication using the Pear Mail function in PHP?
Explain:
If a write this code in a telnet session:
telnet smtp.example.com 25
[...]
mail from: me#example.com
250 2.1.0 Ok
rcpt to: you#fakemail.com NOTIFY=SUCCESS,FAILURE,DELAY ORCPT=rfc822;you#fakemail.com
250 2.1.5 Ok

i received a notification mail with a status code from the receiver smtp server (relayed, failed, etc.) when my smpt server sends the email. Now i want to do the same using Pear Mail, but I can't find where i have tu put this option.
This is my code:
$messageTEXT= "..." // text_message
$messageHTML="..." // html message
$headers=array();
$headers['From'] = "me#example.com";
$headers['To'] = "you#fakemail.com";
$headers['Subject'] = "Test mail";
$headers['X-Mailer']="My PHP mailer";
$headers['X-Priority']=3;
$headers['Errors-To'] = "me#example.com";
$headers['Return-Path'] = "me#example.com";
$headers['Disposition-Notification-To'] = "me#example.com";
$message = new Mail_mime();
$message->setTXTBody($messageTEXT);
$message->setHTMLBody($messageHTML);
$mimeparams=array();
$mimeparams['charset']= "UTF-8";
$mimeparams['text_encoding']="8bit";
$mimeparams['text_charset']="UTF-8";
$mimeparams['html_charset']="UTF-8";
$body = $message->get($mimeparams);
$headers = $message->headers($headers);
$smtp = Mail::factory(
'smtp',
array(
'host' => "smtp.example.com",
'port' => "25",
'auth' => true,
'username' => "myuser",
'password' => "mypass")
);
$mail=$smtp->send($to, $headers, $body);
if (PEAR::isError($mail)) {
print ("Error");
return false;
}

You will have to hack PEAR::Mail and Net::SMTP a bit to get this to work.
The standard Mail_smtp::send() method calls into Mail_RFC822::parseAddressList() which will reject the extra data. Commenting out those lines (around line 274) should get you started.
Then you'll need to hack Net_SMTP::rcptTo() to pass the raw data rather than wrapping it in angle brackets.
Make sure your data is being sanitized somewhere else if you're going to circumvent those methods.
