When using the email integration, when a Deal is closed (won, lost or any other “completed” status) we should be able to stop adding new emails to this Deal.
The problem is, if I close a Deal with a customer and weeks later I create a second Deal, I want new exchanged emails to be linked to the new Deal only, not the one I won and is closed for weeks. At the moment, all emails are attached to both Deals. Over time, I will have a ton of emails linked to old Deals that are closed (won or lost).
