求助大神 phpPHPMailer 邮箱发送失败原因？

Question

$mail = new \PHPMailer(); //实例化
$mail->IsSMTP();
$mail->CharSet='UTF-8'; //设置邮件的字符编码，这很重要，不然中文乱码
$mail->SMTPAuth = true; //开启认证
$mail->Port = 25;
$mail->Host = "smtp.163.com";
$mail->Username = "[e-mail]";
$mail->Password = "123456lh";
//$mail->IsSendmail(); //如果没有sendmail组件就注释掉，否则出现“Could not execute: /var/qmail/bin/sendmail ”的错误提示
$mail->AddReplyTo("[e-mail]","mckee");//回复地址
$mail->From = "[e-mail]";
$mail->FromName = "www.phpddt.com";
$to = "[e-mail]";
$mail->AddAddress($to);
$mail->Subject = "phpmailer测试标题";
$mail->Body = "m）对phpmailer的测试内容";
$mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; //当邮件不支持html时备用显示，可以省略
$mail->WordWrap = 80; // 设置每行字符串的长度
//$mail->AddAttachment("f:/test.png"); //可以添加附件
$mail->IsHTML(true);
$mail->Send();
dump($mail);
echo '邮件已发送';

在错误信息里面有提到，smtp的不能认证，不能连接smtp host。是不是电脑没有网呀？
