Question

我写了一个简单的脚本来通过Gmail SMTP服务器发送电子邮件。代码如下：

import smtplib
msg = 'Hello World!'
server = smtplib.SMTP('smtp.gmail.com', 587) #port 465 or 587
server.ehlo()
server.starttls()
server.ehlo()
server.login('username@googlemail.com','password')
server.sendmail('username@googlemail.com','username@googlemail.com', msg)
server.close()

有时它有效，有时我会收到错误。它是什么原因？我已将Gmail配置为接受安全性较低的应用。如果错误发生，我收到以下消息：

Traceback (most recent call last):
  File "email.py", line 31, in <module>
    server.login('username@googlemail.com','password')
  File "/usr/lib/python3.5/smtplib.py", line 729, in login

我在互联网上找不到任何帮助。非常感谢您的每一条建议。

答案建议首先启用对安全性较低的应用的访问权限。如果这不起作用，您可以尝试访问该页面上提供的链接：https://www.google.com/accounts/DisplayUnlockCaptcha

这可以启用访问。
