[otrs] Notification for closed ticket

Notification for closed ticket Hello, I'm using OTRS 2.4.4 on CenotOS 5.3 x86_64. Could you help me to set the system so that notifications can automatically send to a customer when ticket has been closed? My customer can receive an email when they create a new ticket. I already do the following action: Go into Admin ---> [Notification {Event}] and then create a rule like this: Name: Ticket State Changed Recipient: Customer Event: TicketStateUpdate Priority: select all. State: select both of the "closed" states Queue: select all queues Input Subject and Text for the email at the bottom I check my system log file and just found the sent email history for create new ticket. Thank you very much for your help! Best Regards, Zhang QZ
