This covers a situation where you need to send a secondary, or separate policy violation email notification to email recipients.
Release : 15.8+
Component : Email Prevent
There is no default "recipient" field in response rules.
This can be resolved by creating a separate additional email notification response rule and adding the variable $RECIPIENTS$ in the "Custom To" email box. This will cause Enforce to send a recipient notification each time the response rule is triggered by a policy.
