email类怎么不能使用服务器邮箱，救命啊！！！

gtf505033

    用CI写email发送邮件，很是奇怪，我用个人的gtf505055@163.com可以测试成功，配置如下
    email.php
      $config['protocol'] = 'smtp';
      $config['smtp_host'] = 'smtp.163.com';
      $config['smtp_user'] = 'gtf505055@163.com';
      $config['smtp_pass'] = '*******';
      $config['mailtype'] = 'html';
      $config['validate'] = true;
     $config['priority'] = 1;
     $config['crlf']  = "\r\n";
     $config['smtp_port'] = 25;
     $config['charset'] = 'utf-8';
    $config['wordwrap'] = TRUE;
  控制器文件
   class Email extends CI_Controller {

    function __construct()
{
  parent::__construct();
}
public function index()
{
$this->load->library('email');
$this->email->from('gtf505055@163.com', 'Your Name');
$this->email->to('785965002@qq.com');
$this->email->subject('Email Test');
$this->email->message('Testing the email class.');
$this->email->send();
    echo $this->email->print_debugger();
}
}
这样可以发送成功，可是当我换成企业邮箱的时候
    email.php
      $config['protocol'] = 'smtp';
      $config['smtp_host'] = 'smtp.ym.163.com';//这样的我也试过'smtp.163.com'还是不行
      $config['smtp_user'] = 'service@hxyjw.com';
      $config['smtp_pass'] = '*******';
      $config['mailtype'] = 'html';
      $config['validate'] = true;
     $config['priority'] = 1;
     $config['crlf']  = "\r\n";
     $config['smtp_port'] = 25;
     $config['charset'] = 'utf-8';
    $config['wordwrap'] = TRUE;
  控制器文件
  class Email extends CI_Controller {

    function __construct()
{
  parent::__construct();
}
public function index()
{
$this->load->library('email');
$this->email->from([url=mailto:]'service@hxyjw.com[/url]', 'Your Name');
$this->email->to('785965002@qq.com');
$this->email->subject('Email Test');
$this->email->message('Testing the email class.');
$this->email->send();
    echo $this->email->print_debugger();
}
}
