推荐答案

是你能从你的计算机ping smtp.gmail.com吗？

Are you able to ping smtp.gmail.com from your computer?

你的代码没有问题。

因为你使用的是ASP.NET，你能不能尝试在web.config文件中添加以下内容

There is nothing wrong with your code.
Since you are using ASP.NET, can you try adding the following in web.config file

<system.net>
	<defaultproxy>
		<proxy proxyaddress="ip address of proxy server" />
	</defaultproxy>
</system.net>

错误是自描述的，系统无法从您的计算机访问Smtp.gmail.com。

1.检查防火墙设置

2.尝试从你的机器ping smtp.gmail.com

3.打开命令提示符，然后输入nslookup www.gmail.com 。看看你是否得到回复和域名ip

如果没有那么你的域名设置

The error is self descriptive, system unable to access Smtp.gmail.com from your machine.
1. check firewall settings
2. try pinging Smtp.gmail.com from your machine
3. open a command prompt, and type "nslookup www.gmail.com". see if you get response and domain ip
if not then your domain setting
