custom email headers - cakephp 1.3

Question

How do I go about setting custom email headers within cakephp 1.3?

I am trying the following:

$this->Email->headers = array('X-statusID' => $status_id);

But the header does not exist in the email when I read it using PHP IMAP.

Thanks

Based on what I read in the API documentation, it should just be:

$this->Email->header(array('X-statusID' => $status_id));
