The issue is that when replying to a request's email notification (e.g. to add request participants in the cc), the email is added to the activity of the issue as a reply to customer. And because all replies to customer are indeed sent to customer, the email is sent again which causes a customer to receive 2 identical emails: 1 sent via email and 1 via Jira. Is it possible to avoid this without disabling notifications from Jira since it is primarily used for communication?
