In the context of Message Queuing, messages consist of a body and a set of properties. Message bodies can contain text or any form of binary information, and can be encrypted. Most message properties are specified programmatically by Message Queuing applications. Some properties, such as the sender's security ID (SID) and the message ID, are specified by Message Queuing. Message properties cannot be encrypted. A message, including the body and all specified properties, can be no larger than 4 megabytes (MB) in size. For details, see the following links:
