CakePHP邮件不能正常工作-如何跟踪错误

我使用cakephp电子邮件组件。在我的实时服务器$this->Email->send()返回成功。但是邮件收不到。有什么问题吗?我需要找出错误是什么?我的控制器没有任何模型，这可能会对电子邮件造成任何问题?

        $this->Email->from     = 'Mysitename <no-reply@mysite.com';
        $this->Email->to       =  'sample@gmail.com';
        $this->Email->subject  = "This is test";
        $this->Email->template = 'template_name'; 
        $this->Email->sendAs   = 'html'; 
        ob_start();
        if($this->Email->send())
        {
           $this->log(' Mail Success');
        }
        else
        {
          $this->log('Something broke in mail');    
        }
        ob_end_clean();
