ABSTRACT:
A method and apparatus improve the user-friendliness of messaging systems. A message sender is requested to create a message ID which is used to identify a message being sent by the message sender. At some later time the message sender can query the message center using the sender generated message ID to ask the center to verify whether the message has either been sent to or received by the intended recipient.
