Why doesn't SwiftMailer Symfony2 work on hosting?

Question

symfony

Hello.
I'm trying to set up sending a letter in symfony 2.8 via gmail.
The connection parameters are set like right
config.yml

swiftmailer:
    transport: gmail
    username:  "%mailer_user%"
    password:  "%mailer_password%"

parameters.yml contains login and password respectively. in the docks of the symphony it is said that there is no need to prescribe anything else, all other parameters are pulled up automatically
when you enter the action controller that sends mail, nothing happens (letters do not come, there is also silence in the gmail account, I checked the spam folders)

/**
     * @Route("/email", name="email")
     */
    public function emailAction()
    {

        $message = \Swift_Message::newInstance()
           ->setSubject('Contact enquiry')
           ->setFrom('[email protected]')
           ->setTo('[email protected]')
           ->setBody(
               $this->renderView('TestBundle:Email:registration.html.twig', array('user' => 'user', 'pass'=>'test')),
               'text/html'
           );
       //print_r($message);
        $this->get('mailer')->send($message);

        $em = $this->getDoctrine()->getManager();
        $users = $em->getRepository('TestBundle:User')->findAll();

        return $this->render('TestBundle:Default:admin.html.twig', array(
            'users'=>$users
        ));
    }

at the same time, the standard mail () function passes with a bang in a second
on localhost, the letter in the symphony panel is displayed when I use SwiftMailer
, what's the trouble?

check spool , maybe you have letters in the queue?
