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。我尝试了一个简单的 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，连接超时。

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

这是在 1and1.com 上。我可以在本地主机上设置时发送邮件。

可能出了什么问题：

这是错误日志：

您能否验证您的自定义 EmailTransport 配置并确保您使用的是自定义 EmailTransport 配置而不是默认配置？

在 App.php 中的 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
        ],

    ],

然后在您的控制器内部发送您的电子邮件，如下所示：

    <?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);
          }
    }
