Forward Logs from Cortex Data Lake to an Email Server

Learn how to forward logs from Cortex Data Lake to an email server.
To get email notifications whenever critical issues occur on your network, you can configure Cortex Data Lake to send notifications to an email destination. Cortex Data Lake uses the Palo Alto Networks SMTP server to forward log information in an email format, and all emails are sent from noreply@cs.paloaltonetworks.com. The communication between Cortex Data Lake and the email destination uses SMTP over TLS, and SMTP server certificate is signed by a trusted root CA.
