A mail transfer agent adapted for determining the disposition of incoming e-mail from a sender includes a penalty count filter module which functions on the basis of current communication system resource usage, such as the number of concurrent TCP connections being maintained, and penalty counts assigned for cumulative undesirable sender activity such as sending large e-mail files. The penalty count filter module can operate in a selective-rejection state accepting e-mail from senders without a penalty count and randomly accepting other e-mail, and in a random-rejection state rejecting all e-mail from senders with a penalty count and randomly rejecting other e-mail. The rejection rates can be increased or decreased in response to a detected increase or decrease in the usage of system resources.

Data life cycle policies are developed by classifying data into data classes based upon predetermined data attributes. States are then specified in which the data classes may reside. Components are defined that support one or more of the states. Transfer agents support transferring data from one component to another component. A state transition diagram is prepared for each data class, including one or more conditions that are necessary for each transition between states. An algorithm is applied to the state transition diagram which generates policies that generate life cycle actions if the data or file belongs to the class, the present state of the data or file, and if the conditions for the transitions between the states for each data class have been met. The algorithm provides a method and system for developing data life cycle policies.
