CONTROLLING THROUGHPUT OF MESSAGE REQUESTS IN A MESSAGING SYSTEM

A method, system, and program for controlling throughput of message requests in a messaging system is provided. A message request is received from a sending user. A priority requirement is determined for the message request according to priority settings designated by a receiving user for whom the message request is intended. Output of the message request to the receiving user is adjusted according to whether the message request meets the priority requirement, such that throughput of the message request to the receiving user is controlled. In addition, output of a message indicating that the receiving user is available is adjusted according to said priority requirement.
