Email 服务器不支持SMTP身份验证扩展名

将气流2.0.1与以下

气流.cfg

配置一起使用。我正在尝试发送电子邮件通知。我的gmail帐户已激活双因素身份验证

smtp_host = smtp.gmail.com
smtp_starttls = False
smtp_ssl = False
smtp_user = <my_gmail_user@gmail.com>
smtp_password = <my_password>
smtp_port = 587
smtp_mail_from = <my_gmail_user@gmail.com>
smtp_timeout = 30
smtp_retry_limit = 5

---

尝试将smtp配置更新为

smtp\u starttls=True

所有主要的电子邮件客户端都使用安全连接。关于StartTLS，它是一个协议命令，用于通知电子邮件服务器电子邮件客户端希望使用TLS或SSL从不安全连接升级到安全连接

send_email_notification = EmailOperator(
        task_id='send_email_notification',
        to='<my_another_working_email>@hotmail.com',
        subject='Airflow mail test',
        html_content="<h3> Airflow mail test</h2>"
    )
