Configure the following settings for your remediation actions.

  • Warning Email Template: Add the Sender Email address, the Subject, and the Body for the email you want to send to users when a malicious or suspicious email is detected and automatically remediated. An email body template is provided which you can customize to your organization's needs. The template contains the details of the suspicious email including the sender email address, subject, and the time the email was received.

  • Move to Folder Action: Select a folder to which suspicious mails will be moved. If a folder isn't configured, the email is moved to the default PANW Quarantined folder. If the PANW Quarantined folder doesn't exist, it is automatically created in the mailbox of the user.
