Prevent Appending Email to the Activity Stream of a Closed Incident

[Ross Drew]

I am being asked to prevent an email reply from being appended to the activity stream of a closed (active = false) incident ticket. I have stopped the commenting when the incident is closed, but cannot figure out how to prevent the email from being appended to the close incident ticket. Has anyone done this? Would this create larger issues / technical debt?

You can add the filter condition to the inbound email action filtering out inactive incidents.
sysevent_in_email_action - Update Incident

That only stops adding any comments or work notes. I did that and no work notes or comments are written, but the email is still showing in the activity stream. The requirement is to stop that as well.
