使用 smtplib 库发送电子邮件时出现超时错误

Question

这是我的代码：

import smtplib

connection = smtplib.SMTP("smtp.gmail.com")
connection.starttls()
connection.login(user="mymail@gmail.com", password="mypassowrd")
connection.sendmail(from_addr="mymail@gmail.com", to_addrs="recievermail@gmail.com", msg="Hello")
connection.close()

所以我收到了这个错误：

Traceback (most recent call last):
  File "E:0Days-Python_programs\Day32\Birthday Wisher (Day 32) start\main.py", line 3, in <module>
    connection = smtplib.SMTP("smtp.gmail.com")
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\smtplib.py", line 253, in __init__
    (code, msg) = self.connect(host, port)
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\smtplib.py", line 339, in connect
    self.sock = self._get_socket(host, port, self.timeout)
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\smtplib.py", line 310, in _get_socket
    return socket.create_connection((host, port), timeout,
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\socket.py", line 843, in create_connection
    raise err
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\socket.py", line 831, 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

Process finished with exit code 1

我开启了不太安全的应用程序访问：

我也关闭了所有安全步骤：

而且我也关闭了防火墙保护。

但没有任何效果。

所以请有人帮助我。

您需要指定端口。在这种情况下，它是 587 for TSL.

不知何故它起作用了，但我没有深厚的知识来解释为什么。

我遇到了同样的问题，所以有一个解决方案：

connection = smtplib.SMTP("smtp.gmail.com", 587)
