I'm trying to add a few Ticket Notification Events, specifically, one that will notify our entire support team of a new ticket creation, as well as when a customer follows up on an already created ticket.
We're using OTRS 2.4.7

I created a notification on "TicketCreate", and a notification (with a different body text) on "TicketCustomerUpdate". But now, new tickets from customers result in two e-mails for a single event. I'm assuming this is because the logic works out that a "Customer" "Updated" a ticket, by creating it, which is patently false.

Is this considered expected behavior? A bug? Or something else entirely?

My current solution is to set the "TicketCreate" notification to invalid (or delete it), which I don't like, because occasionally an Agent will create a ticket on behalf of a customer, but that will result in no notifications going out as a result. Is there a middle ground I'm missing?
