You can set delivery to debug to see an output of your message to make sure it's fine:

$this->Email->delivery = 'smtp';

And you also need to setFlash('email') to see the output in your view:

echo $this->Session->flash('email');

As far as emailing from a live server goes - there's a very good chance the server or IP is blacklisted and you'll need to get it to pass various checks before your sent messages can be received:
