YII2 email configuration, the online method is ineffective!

Check my configuration item {code...} And then upload my sending code {code...}. How can I test it? Is my posture incorrect ?! First go to my Configuration item

'mailer' => [        'class' => 'yii\swiftmailer\Mailer',        'viewPath' => '@common/mail',        'useFileTransport' => true,        'transport' => [            'class' => 'Swift_SmtpTransport',            'host' => 'smtp.163.com',            'username' => 'username@163.com',            'password' => 'myPassword',            'port' => '994',            'encryption' => 'ssl',        ],    ],

Then go to mySend code

return \Yii::$app->mailer->compose('passwordResetToken', ['user' => $user])    ->setFrom([\Yii::$app->params['supportEmail'] => \Yii::$app->name . ' robot'])    ->setTo($this->email)    ->setSubject('Password reset for ' . \Yii::$app->name)    ->send();

The test is invalid. Is it me?PostureNo ?!

'Usefiletransport '=> true,

Change to false. If it is true, ONLY emails are generated at runtime.

I think Yii2 is not very stable yet. Currently, it cannot be used in the production environment.

It seems that the email address set by \ Yii: $ app-> mailer's setFrom () must be the same as the email address in the configuration.
