This is the scenario:
1. Client will send an email to whd email regarding an issue - let's say the subject is "Issue 1"
2. WHD will create a ticket and send an email to the client with a subject "Ticket #1 - Issue 1"
3. Client will reply from his previous email and not from the email of whd - subject will become "RE: Issue 1"
4. Whd will create another ticket for the same issue
I believe this is possible with using the Filter in the email options. We had created a filter "(?i)RE:" this should block tickets with RE: or re: on the subjects but when we tested it tickets are still being created.
I would like to ask for help regarding this because this is really affecting our system. We already so much cancelled tickets because of this
