The problem is that the DNS lookup for 'smtp server name' is failing - if this is your exact code then you can see why - if not and you have the valid qualified name for the SMTP server then you may have issues with the firewall/internet connection, etc., also port has to be set to a valid value to match your servers SMTP configuration, (usually port 25 butnot absolutely always).
问题是“smtp 服务器名称”的 DNS 查找失败 - 如果这是您的确切代码，那么您可以看到原因 - 如果不是，并且您拥有 SMTP 服务器的有效限定名称，那么您可能遇到防火墙问题/互联网连接等，还必须将端口设置为有效值以匹配您的服务器 SMTP 配置（通常是端口 25，但并非绝对总是如此）。

I know for sure that gaierror comes up when you are working from behind proxy.
我确信当您从代理后面工作时会出现 gaierror。

You need to login using your credential. Try:
您需要使用您的凭据登录。尝试：
smtpObj = smtplib.SMTP('smtp server name',port)
smtpObj .starttls()
smtpObj .login(email, password)
smtpObj.sendmail(sender, EmailId, message, msg.as_string() )
print "Successfully sent email"

In my case was a hostproblem. Using debug mode, I spotted that in (host, port, 0, SOCK_STREAM) I got host=localand it should be host=localhost. In the run.py I defined localhostand the file hosts (c:\windows\system32\drivers\etc\hosts) was defined local. They have to be equal, otherwise you get the socket.gaieeror.
就我而言，是主机问题。使用调试模式，我发现在 (host, port, 0, SOCK_STREAM) 我得到了host=local，它应该是host=localhost。在 run.py 中，我定义了localhost并且文件 hosts (c:\windows\system32\drivers\etc\hosts) 被定义为local。它们必须相等，否则你会得到 socket.gaieeror。

I prefer u guys to run the file as administrator for eg open cmd as administrator then type cd C:\into ur .py file pathand then type python filename.py
我更喜欢你们以管理员身份运行文件，例如以管理员身份打开 cmd 然后输入 cd C:\into ur .py 文件路径，然后输入 python filename.py
it worked for me. good luck
它对我有用。祝你好运

There seems to be a bug in urllib3 version 1.25.9 package. This produced "socket.gaierror: [Errno 11001] getaddrinfo failed" error for me (working from behind an authenticated proxy server). Downgrading to urllib3 version 1.25.8 solved the problem.
urllib3 版本 1.25.9 包中似乎存在一个错误。这对我产生了“socket.gaierror: [Errno 11001] getaddrinfo failed”错误（在经过身份验证的代理服务器后面工作）。降级到 urllib3 版本 1.25.8 解决了这个问题。
