错误：[Cake \ Network \ Exception \ SocketException]连接超时

Question

我无法从我的cakephp 3网站发送邮件。我尝试了一个simiple testmail.php文件，我收到了电子邮件，但是当我尝试在app.php上设置相同的用户名和密码时，我正在连接超时。

Error: [Cake\Network\Exception\SocketException] Connection timed out 

这是1and1.com。在本地主机上设置时，我可以发送邮件。

什么是错的：

这里是error.log中：

能否请您确认您的自定义EmailTransport配置，并确保您使用您的自定义配置EmailTransport，而不是默认的一个？

在App.php EmailTransport配置应该是这样的：

'EmailTransport' => [ 
     'default' => [ 
      'className' => 'Mail', 
      // The following keys are used in SMTP transports 
      'host' => 'localhost', 
      'port' => 25, 
      'timeout' => 30, 
      'username' => 'user', 
      'password' => 'secret', 
      'client' => null, 
      'tls' => null, 
      'url' => env('EMAIL_TRANSPORT_DEFAULT_URL', null), 
     ], 
     'custom' => [ 
      'className' => 'Smtp', 
      // The following keys are used in SMTP transports 
      'host' => 'A.B.C.D', // Ip of your server 
      'port' => XX, // Port that you use: 25 or 465 or 587 
      'timeout' => 60, 
      'username' => 'MyUsername', 
      'password' => 'MyPassword', 

      'client' => null, 
      'tls' => true, 
      'url' => env('EMAIL_TRANSPORT_DEFAULT_URL', null), 
     ], 
     'debug' => [ 
      'className' => 'Debug', 
      // The following keys are used in SMTP transports 
      'host' => 'A.B.C.D', // Ip of your server 
      'port' => XX, // Port that you use: 25 or 465 or 587 
      'timeout' => 60, 
      'username' => 'MyUsername', 
      'password' => 'MyPassword', 

      'client' => null, 
      'tls' => null, 
      'url' => env('EMAIL_TRANSPORT_DEFAULT_URL', null), 
     ], 
     'gmail' => [ 
      'host' => 'ssl://smtp.gmail.com', 
      'port' => 465, 
      'timeout' => 30, 
      'username' => 'test@gmail.com', 
      'password' => 'password_of_test', 
      'headers' => array(
       'X-Mailer' => 'PHP' 
      ), 
      'charset' => 'UTF8', 
      'headerCharset' => 'UTF8', 
      'className' => 'Smtp', 
      'tls' => null 
     ], 

    ], 

而且你的控制器内发送的邮件是这样的：

<?php 
    namespace App\Controller; 

    use Cake\Mailer\Email; 
    /* ... */ 

    private function sendResetEmail($msg, $user) { 

     $email = new Email(); 
     $email->transport('custom'); // Here we call to ou custom config 

     $email->template('YourEmailTemplate'); 
     $email->emailFormat('both'); 
     $email->from('noreply@example.com'); 
     $email->to($user->email, $user->username); 
     $email->subject('Reset your password'); 
     $email->viewVars(['msg' => $msg, 'username' => $user->username]); 
     try { 
      $email->send(); 
      } catch(Exception $e) { 
      throw new Exception("Exception caught with message: " . $e->getMessage().'\n'.$email->smtpError); 
      } 
    } 

希望它可以帮助
