zend邮件无法在社交引擎中工作

Question

我正在尝试在社交引擎控制器中设置我自己的发送邮件功能。失败没有错误。请帮忙！

以下是我用来发送邮件的代码。我把它放在分类索引控制器里面。

use Zend\Mail\Message;
use Zend\Mail\Transport\Smtp as SmtpTransport;
use Zend\Mail\Transport\SmtpOptions;

    $message = new Message();
$message->addTo('to@email.com')
        ->addFrom('from@email.com')
        ->setSubject('Greetings and Salutations!')
        ->setBody("Sorry, I'm going to be late today!");

      // Setup SMTP transport using LOGIN authentication
      $transport = new SmtpTransport();
      $options   = new SmtpOptions(array(
        'name'              => 'localhost.localdomain',
        'host'              => 'smtp.mandrillapp.com',
          'port' => '587',
        'connection_class'  => 'login',
        'connection_config' => array(
        'username' => 'my@email.com',
        'password' => '*********',
    ),
));
$transport->setOptions($options);
$transport->send($message);

谢谢！
