Sun Java System Messaging Server 6.3 Administration Guide Defining and Using Message Types

You define a message type by giving it a unique definition such as multipart/voice-message. By default, the message store reads the Content-Type header field to determine the message-type. If you prefer, you can configure a different header field to identify the message types.

The message store reads the Content-Type (or other specified) header field, ignoring case. That is, the message store accepts the header field as valid even if the header's combination of uppercase and lowercase letters differs from the expected combination.

The message store reads only the message-type name in the header field. It ignores additional arguments or parameters.

To define a message type, use the configutil utility to set values for the store.messagetype parameters. For instructions, see To Configure Message Types.

These tasks are summarized in the following sections:
