I am setting up osTicket to create tickets when it receives an email from an automated system. The reply to address for the email does not have an actual mailbox, it's just a made up address that indicates the source of the ticket. Since the client email address is not valid, when update emails are sent to the client an undeliverable message is generated, which in turn creates a new ticket based off of that email. Is it possible to disable emails being sent to the client since there is no real client in this scenario?
