since v10.0.138The extension point IncomingMessageReceivedEventListener is a java interface that can be implemented to perform actions after the message has been received but before it is being processed by the knowledge base.
Your plugin receives an IncomingMessageReceivedEvent that provides additional information about the received message.
Your plugin may add additional data to the storage of the ticket, that will be created after the message has been successfully processed by the knowledge base.
Alternatively you can pass transient data via the IncomingBindings to other plugins or the knowledge base.
