SMTP 行为怪异

Question

我正在尝试在 python 中使用 SMTPLIB 发送消息，但是我收到一条错误消息。我很肯定使用的电子邮件和密码是正确的。我尝试通过网络浏览器登录和不登录来发送这个。正如以下 stackoverflow 文章所述：Error sending email: raise SMTPAuthenticationError(code, resp)。我在下面的代码中替换了单词而不是实际的电子邮件和密码：

import smtplib

server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login("senderemail", "senderemailpassword")

msg = "Hello!"
server.sendmail("senderemail", "recieveremail", msg)
server.quit()

错误信息：

Traceback (most recent call last):

    server.login("senderemail", "senderpassword")

如果有人可以修复我的代码，那将非常有帮助。

默认情况下，Google 会阻止来自不使用现代安全标准的脚本/应用程序的任何登录尝试。但是，您可以更改该设置：https://www.google.com/settings/security/lesssecureapps。
