Yii2 not sending email?

Question

Yii

I configured smtp and still the email is not sent

'mailer' => [
             'class' => 'yii\swiftmailer\Mailer',
              'viewPath' => '@app/mail',
              'transport' => [
                  'class' => 'Swift_SmtpTransport',
                  'host' => '212.224.124.72',
                  'username' => '[email protected]',
                  'password' => '123456789',
                  'port' => 25,
                  'encryption' => 'ssl',
              ],
              'useFileTransport' => false,
        ],

Answer 1

this is more a configuration question than Yii.
Check if the port is different or
'encryption' => 'tls',

Answer 2

Good evening.
'useFileTransport' => true
