推荐答案
辩诉se使用本地电子邮件服务器进行测试： http://www.hmailserver.com/ [ ^ ]
它是免费的。
您的提供商将限制访问pop / smtp的次数，如果您尝试使用奇怪的命令拍摄SMTP / POP，也可能完全禁止您。
你的例外
Please use a local Email-Server for testing: http://www.hmailserver.com/[^]
It's free.
your provider will limit the number of accesses to the pop/smtp and might also ban you completely if you try to shoot the SMTP/POP with strange commands.
Your Exception
The remote name could not be resolved: 'wmail.link.net' < br $>
表示该地址不存在或者至少无法解析为IP地址。
says that the address is not existing or at least can not be resolved to an IP address.
此错误消息相当不言自明：无法解析远程名称：'wmail.link.net'
您无法创建与SMTP服务器的连接已经指定。
您的代码没有任何问题。您只需要检查无法访问SMTP的原因（'wmail.link.net'）服务器
对于初学者，尝试从运行应用程序的计算机上ping wmail.link.net。
This error message is quite self-explanatory:The remote name could not be resolved: 'wmail.link.net'
You cannot create a connection to the SMTP server you have specified.
There is nothing wrong with your code. You just need to check why you can't access the SMTP ('wmail.link.net') server
For starters, try pinging wmail.link.net from the machine your application is running on.
如果你无法连接到任何smtp，你应该咨询你的网络部门，因为它似乎是您和提供商之间的防火墙的一般问题。您也可以尝试禁用本地Windows防火墙。
您也可以在 System.Net.Mail.SmtpException：发送邮件失败 [ ^ ]
If you cannot connect to any smtp you should consult your network department because it seems to be a general problem with a firewall between you and your provider. You can also try to disable your local windows firewall.
Also you can refer the same question in System.Net.Mail.SmtpException:Failure sending mail[^]
