Question

首先，我（无论如何）都是Python的新手，并且从程序员的角度浏览电子邮件的复杂性。因此，如果我省略任何重要信息或滥用任何术语，请不要犹豫让我澄清一下！

我最近学习了如何通过Python 3.7（在Windows 10操作系统上）从家庭Internet网络中毫无问题地生成和发送电子邮件。但是，当我在公司的Internet网络上时，无法正确连接Python以生成和发送电子邮件。我将在下面显示我尝试过的两种不同方法（均来自先前的论坛主题），以及后续的错误消息：

import smtplib

server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
server.login("aaron.dadas.85", "mypassword")
server.sendmail(
  "aaron.dadas.85@gmail.com", 
  "aaron.dadas.85@gmail.com", 
  "this message is from python")
server.quit()


Traceback (most recent call last):
  File "C:\Users\320045759\Desktop\emailtest.py", line 3, in <module>
    server = smtplib.SMTP_SSL('smtp.gmail.com', 465)

    self.sock = self._get_socket(host, port, self.timeout)

    self.source_address)

    raise err
  File "C:\Users\320045759\Desktop\Softwares\Python\Python37\Lib\socket.py", line 716, in create_connection
    sock.connect(sa)
TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

这是第二次尝试，使用我公司的Internet代理：

import smtplib
import socks

socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, 'http://user:password@199.168.151.10:80', 8080)
socks.wrapmodule(smtplib)

smtpserver = 'smtp.gmail.com'
AUTHREQUIRED = 1 
smtpuser = 'aaron.dadas.85'  
smtppass = 'mypassword'  

RECIPIENTS = 'aaron.dadas.85@gmail.com'
SENDER = 'aaron.dadas.85@gmail.com'
mssg = "test message"
s = mssg   

server = smtplib.SMTP(smtpserver,587)
server.ehlo()
server.starttls() 
server.ehlo()
server.login(smtpuser,smtppass)
server.set_debuglevel(1)
server.sendmail(SENDER, [RECIPIENTS], s)
server.quit()


Traceback (most recent call last):
  File "C:\Users\320045759\Desktop\Softwares\Python\Python37\Scripts\socks.py", line 823, in connect
    super(socksocket, self).connect(proxy_addr)
socket.gaierror: [Errno 11003] getaddrinfo failed

During handling of the above exception, another exception occurred:

我曾尝试导航其他线程以寻求解决方案，但是其中许多都由用户禁用防火墙来解决（通常在用户收到“ [WinError 10061]无法连接，因为目标计算机处于活动状态时无法建立连接的情况下）拒绝”错误-在这种情况下，我也多次遇到此错误）。我不能禁用防火墙。我无权更改公司设置，因此必须绕过公司防火墙。

说实话，这可能根本不是问题。我觉得好像只是在处理应该如何使用网络的代理地址一样。一个重要的提示是，当我从命令行使用 python -m pip install [package] 时，它每次都会失败。但是，当我使用 python -m pip --proxy http://user:password@199.168.151.10:80安装[package] 时，它可以工作。如果我正确地理解了这一点，则意味着可以使用一种代理地址来访问在线资源...在生成/发送电子邮件的情况下，我只是没有正确地使用代理地址。

我希望此介绍内容能为有人提供足够的帮助！我将积极监视答复，以在需要时提供更多信息。谢谢！

编辑01/07/2019：

使用以下脚本，我可以在公司Internet上提取HTML代码（使用代理设置）：

import requests
proxies = {'http': 'http://user:password@199.168.151.10:80','https': 'http://user:password@199.168.151.10:80'}
r = requests.get('https://www.google.com/', proxies=proxies)
print(r.text)

[输出的是Google主页HTML代码]

这是朝正确方向迈出的一步，因为它表明了通过此代理地址成功连接到Internet。但是我仍然无法解决这个难题：在我之前的尝试中，什么缺失或语法上不正确？我是否不正确地声明了代理地址？

使用代理使用Python发送电子邮件（无法禁用防火墙）
