Airflow会发送这类错误的电子邮件吗？如果没有,发送这些错误的电子邮件的最佳方式是什么？

我甚至不确定airflow.cfg是否设置正确…由于最终目标是测试电子邮件警报通知,我想确保正确设置airflow.cfg.这是设置：

[email]
email_backend = airflow.utils.email.send_email_smtp


[smtp]
# If you want airflow to send emails on retries,failure,and you want to use
# the airflow.utils.email.send_email_smtp function,you have to configure an
# smtp server here
smtp_host = emailsmtpserver.region.amazonaws.com 
smtp_starttls = True
smtp_ssl = False
# Uncomment and set the user/pass settings if you want to use SMTP AUTH
# smtp_user = airflow_data_user
# smtp_password = password
smtp_port = 587 
smtp_mail_from = airflow_data_user@domain.com

什么是smtp_starttls？我在文档或在线中找不到任何相关信息.如果我们有查看电子邮件所需的双因素身份验证,那么这对Airflow来说是个问题吗？

这是我的Bash命令：

task1_bash_command = """
export PATH=/home/ubuntu/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin
export rundate=`TZ='America/Los_Angeles' date +%F -d "yesterday"`
export AWS_CONFIG_FILE="/home/ubuntu/.aws/config"

/home/ubuntu/bin/snowsql -f //home/ubuntu/sql/script.sql 1> /home/ubuntu/logs/"$rundate"_dev.log 2> /home/ubuntu/logs/"$rundate"_error_dev.log

if [ -e /home/ubuntu/logs/"$rundate"_error_dev.log ]
then
    exit 64
fi

我的任务是：

task1 = BashOperator(
    task_id = 'run_bash',bash_command = task1_bash_command,dag = dag,retries = 2,email_on_failure = True,email = 'username@domain.com')
