Notifications can deliver status information about messages of different types, such as text messages, voice mail, and image data. Messaging Server uses Sun Java System Message Queue to send notification information for message types. For information about configuring the JMQ notification plug-in for Message Queue, see Chapter 22, Configuring the JMQ Notification Plug-in to Produce Messages for Message Queue
To enable the JMQ notification plug-in to recognize a particular message type, you must configure the store.messagetype parameters, including the store.messagetype.x.flagname parameter. For details, see To Configure Message Types.
Once the message types have been configured, JMQ notification messages can identify the particular message types. You can write a Message Queue client to interpret notification messages by message type and deliver status information about each type to the mail client.
The JMQ notification function counts the number of messages currently in the mailbox, by message type. Instead of sending one count, an array specifying the count for each message type is sent with the notification message.
For example, a NewMsg notification message can carry data to tell the user that, for example, there are seven new voice mail messages and four new text messages in the user's inbox.
