        Note that if you turn on the Yii debugger, you should be able
        to view the mail message on the mail panel of the debugger.
        <?php if (Yii::$app->mailer->useFileTransport): ?>
        Because the application is in development mode, the email is not sent but saved as
        a file under <code><?= Yii::getAlias(Yii::$app->mailer->fileTransportPath) ?></code>.
        Please configure the <code>useFileTransport</code> property of the <code>mail</code>
        application component to be false to enable email sending.
