本文实例为大家分享了python自动发送报警监控邮件的具体代码，供大家参考，具体内容如下

因为有一些日常任务需要每日检查日否执行正确，所以需要一个报警监控的机制，这个需要你指定你发送的邮箱和你接收的邮箱，就可以使用了。

这四个需要填写一下，我们使用的qq企业邮箱所以host为smtp.exmail.qq.com

mail_host=""
mail_user=""
mail_pass=""
mail_postfix=""

使用如下，也可以增加附件使用。

python send_email.py xxxxxxx@qq.com,xxxxxx@qq.com test数据 /home/data/test/sendfile

python代码：
