电子邮件未发送到hotmail帐户使用yii2 swiftmailer

Question

虽然从我的网站发送电子邮件发送到gmail帐户但电子邮件未发送到Hotmail帐户，我在yii2配置文件中使用yii2 swift邮件程序配置

`mailer' => [
      'class' => 'yii\swiftmailer\Mailer',
      'viewPath' => '@common/mail',
      'useFileTransport' => false,
      'transport' => [
            'class' => 'Swift_SmtpTransport',
            'host' => 'mail.sample.in',
            'username' => 'develop@sample.in',
            'password' => 'dev98761XXX',
            'port' => '25',
            'encryption' => 'tls',
      ],
],
