为什么我收到此错误smtplib.SMTPAuthenticationError

问题描述

这是我面临的错误。我为此使用了应用程序密码（甚至尝试过安全性较低的应用程序），但是它无法正常工作。早些时候它运行良好，但是由于2-3天，它给出了此错误。我想使用smtp代替aouth，所以请您帮帮我。

这是代码：

token = user.get_reset_token()
    message = MIMEMultipart("alternative")

    message["From"] = "Test <Config.MAIL_USERNAME>"
    message["To"] = user.email

    # Create the plain-text and HTML version of your message
    text = """\

    html = u"""\

    # Turn these into plain/html MIMEText objects
