smtp - Error message when using SwiftMailer with Laravel -

i'm trying send emails (gmail) using built in swiftmailer bundle laravel 4. i've been able send , receive emails on local server, when live, keep receiving error message:

failed authenticate on smtp server username "info@myemail.com" using 2 possible authenticators 

here's controller:

public function show_sent() {      $name = input::get('name', 'someone');     $email = input::get('email');      // i'm creating array user's info can use $user->email or pass $user object closure later     $user = array(         'email'=>'info@myemail.com',         'name'=> $name     );      // data passed mail view blade template     $data = array(         'detail'=>'visitor\'s website enquiry',         'name'  => $user['name'],         'email'=> $email     );      // use mail::send function send email passing data , using $user variable in closure     mail::send('emails.registration', $data, function($message) use ($user)     {       $message->from('info@myemail.com', 'someone');       $message->to($user['email'], $user['name'])->subject('new site registration');     });      $view = view::make('sent');     $view->title = 'sent';     $view->keywords = 'to complete';      $view->description = 'to complete'; $view->body_id = 'sent-page';     return $view;        } 

mail.php settings:

'driver' => 'smtp', 'host' => 'smtp.gmail.com', 'port' => 465, 'encryption' => 'ssl',
