[otrs] Notification on ticket close?

Hello, I have been trying, unsuccessfully, to obtain a notification from OTRS (v6.0.3 Free) when a ticket is closed. I do receive automatic notifications when a new ticket is created, pending reminders, etc. I added a notification type in the Ticket Notification Management screen, and have tried various event triggers with filters etc to capture a "ticket close event". All the standard notifications seem to use a "Notification**" event type, but I have not found the applicable event for closing a ticket. Help appreciated, or let me know if this is the wrong approach. Thanks, -arun -- Arun Venkataraman, Arecibo Observatory/HC3 Box 53995/Arecibo, PR 00612 arun@naic.edu
