I have set the e-mail under settings but I am not reciving any information about detections which I see in the portal.
The problem was caused by bad e-mail configuration on my part. Trying another e-mail address worked right away.
If you are using HTTP proxy in your environment, you need to configure your HTTP proxy from the Elements Endpoint Protection Portal for email alerting to work. How to configure EPP for Computers or EPP for Servers:
Once the proxy address has been configured to the device profile and the profile has been taken into use by the devices, wait for a few hours and check with an eicar file if an email alert is now sent to the recipients.
Email alerting configuration instructions can be found in this Help Guide.
I am not using HTTP proxy. I should have specified that I use Endpoint Detection and Response portal and the only place to enter my alert e-mail is under settings but there are no notifications for Detections shown in the portal.
