CI框架 Email类 使用QQ企业邮箱发件失败

正常步骤配置以下几项即可：

        $config['protocol']  = $this->ci->config->item('email_protocol');  
        $config['smtp_host'] = $this->ci->config->item('email_smtp_host');  
        $config['smtp_user'] = $this->ci->config->item('email_smtp_user');  
        $config['smtp_pass'] = $this->ci->config->item('email_smtp_pass');

而CI默认的换行符配置项如下：

        $config['crlf'] = "\n";
        $config['newline'] = "\n";

腾讯企业邮不支持，需要初始化如下：

        $config['crlf'] = "\r\n";
        $config['newline'] = "\r\n";

祝好运
