We use Zoho to communicate with our end users as well as our vendors. It would appear that one of our vendors is also using Zoho desk and some ticket system which is creating a never ending loop of new ticket creation on our side as well as theirs. We sent them an email and their system generated a ticket on their side and send us an email which caused our system to create a new ticket & respond back to them starting the circle of never ending ticket creation. How do we stop this?
