在本机用phpmailer发送邮件有关问题

在本机用phpmailer发送邮件问题
我在本机上用的WampServer Version 2.1版本作为php服务器，来测试phpmailer发送邮件。我下载了最新的class.phpmailer.php和class.smtp.php文件，新建了个php文件phpmail.php来测试发送邮件功能，代码如下：
require_once('class.phpmailer.php');
include("class.smtp.php");

$mail = new PHPMailer(); //建立邮件发送类
$address = $_POST['address'];
$mail->SMTPDebug=true ;
$mail->IsSMTP(); // 使用SMTP方式发送
$mail->CharSet = "UTF-8"; //chinese;
$mail->Host = "smtp.163.com"; // 局smtp服务器
$mail->SMTPAuth = true; // 启用SMTP验证功能
$mail->Username = "cnmhg168"; // 用户名(请填写完整的email地址)
$mail->Password = "******"; // 密码

$mail->From = "cnmhg168@163.com"; //邮件发送者email地址
$mail->FromName = "化工网";
$mail->AddAddress("mysimpledesign@163.com", "tttt");//收件人地址

//$mail->AddAttachment("/var/tmp/file.tar.gz"); // 添加附件
$mail->IsHTML(true); // set email format to HTML //是否使用HTML格式

$mail->Subject = "PHPMailer测试邮件"; //邮件标题
$mail->Body = "Hello,这是测试邮件,百度"; //邮件内容
$mail->AltBody = "from 火星"; //附加信息，可以省略
//$mail->SMTPDebug;

if(!$mail->Send())
{
echo "邮件发送失败.

";
echo "错误原因: " . $mail->ErrorInfo;
exit;
}

echo "邮件发送成功";


?>
用户名和密码没问题，但是提示如下错误信息，不知道哪里有问题，求大家给解决下？
