[otrs] No Notification for Tickets created in Customers Web Interface

Hi, I setup OTRS with several queues, My agents receive a notification for new tickets in those queues if they are created by email, however they dont receive notification if tickets are created by customers via customer web user interface. If the Customer creates them in Raw we do get Notification though. Is this normal, how can i turn on Notifications for those tickets? Thanks, Bulent Oktem
