Abstract
A presence system is used to monitor the presence state of an electronic message originated by a sender and addressed to a recipient. The presence system includes a presence user agent and a presence server. The presence user agent is coupled to a communication network to receive the electronic message, register the electronic message with the presence server as a message presentity, determine presence information for the message presentity and provide the presence information to the presence server. The presence information defines a presence state of the message, in which the presence state identifies a processing state of the electronic message by the recipient. The presence server is also coupled to the communication network to provide the presence information in real-time to watchers of the message presentity.
