Issue/Introduction

Parent domain (example symantec.com) and child domain (example. abc.symantec.com) are registered to the service.

Environment

Email Security.cloud

Resolution

Create Email Data Protection (DP) policy

1. Create Policy 1 as a Global or Custom to symantec.com
2. Set Custom but no policy created to abc.symantec.com
3. Started email processing by DP then Policy 1 is detected by mails of symantec.com.
   1. No emails of abc.symantec.com expected to detect any DP policy but Policy 1 is detected.

Add a DP policy to child domain and activate it. Any kind of dummy policy will work if you do not have a specific policy to process. For example, a policy with setting [Action: Log Only] does not harm email delivery.
