Hi, I am pretty new to OTRS. We implemented the OTRS system a week back and everything was working great. The Customer Notification, Agent Notification, etc. But, from Friday onwards my Agent Notification stopped working. Any a time a new ticket is created, I no longer get any emails. The following is how I have setup the Queues 1. HR - Queue by itself and valid 2. Support - Queue by itself and valid 3. Raw - Invalid 4. Postmaster - Invalid I have enabled Customer Groups mapping in the Config.pm file so that I can assign certain customers to HR alone and certain others to Support alone or both. In my Agent Preferences I have made sure that I have selected all the queues and updated it (highlighted each and every queue). Made sure that I also enabled New Ticket, Follow Up, Ticket lock, Move notifications are set to yes. I am not sure why the Agent Notification has stopped working. I haven't enabled SMTP, again this is not going to help much because the Customer Notifications are working. Any help is wonderful. Magesh.
