cant send email

I cant send an email as I get a generic error
Error: An Internal Error Has Occurred.

In config\email.php I have this for a real gmail account(pswd hidden)
 
          public $gmail = array(
        'host' => 'smtp.gmail.com',
        'port' => 465,
         'username' => 'jagguy999@gmail.com',
       'password' => 'XXXXX',
        'transport' => 'Smtp',
        'tls' => true
    );

in controller I have


App::uses('CakeEmail', 'Network/Email');

 public $components = array('Email','Session','Paginator');
 
public function test() {
    
     $Email = new CakeEmail();
$Email->from(array('jagguy999@gmail.com' => 'My Site'));
$Email->to('jagguy999@gmail.com');
$Email->subject('About');
$Email->send('My message');
    
    
 }
