This article offers a way in which customers of the Email Security .cloud Service (ESS) can implement an alternative to the Anti-Spam service Newsletter Detection feature by using Data Protection, where they can configure exceptions and filters based on the header and body contents of the emails.
The solution is designed for situations where the white listing capability of the Anti-Spam service (addresses, domains and IPs/IP Ranges) cannot fully cover all of the particular newsletter type email filtering requirements.
NOTE: The Data Protection policy based solution does not fully replace the advanced newsletter detection algorithms that are found within the Anti-Spam service Newsletter Detection feature. Tweaking and monitoring are required to achieve optimal results.
Data Protection service available
To create an exclusion condition with emails, we first need to create a custom group
Access Services > Anti-Spam and uncheck the option next to Use Newsletter / Marketing detection.
