PHPMailer错误:SMTP->；错误:无法连接到服务器

我整个上午都在谷歌上搜索，我想我现在需要Stackoverflow！

我写了一个简单的脚本来发送邮件（从hotmail到gmail）但是我得到了这个错误：

SMTP->错误：无法连接到服务器：连接尝试失败，因为连接方在一段时间后没有正确响应，或者由于连接的主机无法响应而建立的连接失败。（10060）SMTP Connect（）失败。错误

这是代码：

<?php
require_once("../includes/phpMailer/class.phpMailer.php");
require_once("../includes/phpMailer/class.smtp.php");

$to_name = "RECEIVER NAME";
$to = "RECEIVER@gmail.com";

$subject = "Mail test at " . strftime("%T", time());
$message = "This is a test message";
$message = wordwrap($message, 70);

$from_name = "MY NAME";
$from = "MY_EMAIL@hotmail.it";

$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPDebug  = 2;
$mail->Host = "smtp.live.com";
$mail->Port = 25;
$mail->SMTPAuth = true;
$mail->Username = "MY USERNAME (hotmail)";
$mail->Password = "MY PASSWORD (hotmail)";

$mail->FromName = $from_name;
$mail->From = $from;
$mail->AddAddress($to, $to_name);
$mail->Subject = $subject;
$mail->Body = $message;
$result = $mail->Send();
echo $result ? 'Sent' : 'Error';
?>

另一个信息是，即使是标准的mail（）函数也不起作用，检查php信息我发现：

sendmail_from-我的正确邮件（hotmail）

sendmail_path-无值

SMTP-localhost

smtp_port-25

谢谢！！
