Hi,
Your example doesnt do anything with the messages, so you will just get a blank page.
I have tested it here:
dixon.io/_testbed/francisco.php
..and it errors. If you can contact me directly with your password, I can test it further for you, as long as you trust me with it.
Failing that, remove the closing php statement at the end of the file (you dont need it) and add:
print_r($email->messages);
