电子邮件未送达Outlook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Outlook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',
  ],
],
