email - 服务器不支持 Airflow SMTP AUTH 扩展

问题描述

使用具有以下airflow.cfg配置的 Airflow 2.0.1。我正在尝试发送电子邮件通知。我的 gmail 帐户 2 因素身份验证已激活。

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

我的电子邮件任务

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>"
    )

但我收到以下错误。在气流安装期间，我指定admin@vbo.local为管理员用户邮件，但实际上并不存在。我不确定这是错误的原因。

解决方案

尝试将 smtp 配置更新为smtp_starttls = True 所有主要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想要从不安全的连接升级到使用 TLS 或 SSL 的安全连接。
