Integrating heterogeneous local mail systems

A description is given of the Heterogeneous Mail System. This environment is inexpensive to implement. It is also inexpensive to integrate a new mail system into the environment and to use its services effectively. Diverse classes of mail systems can be integrated into the environment. The system model is examined, with particular attention to the mail semantic managers, the system server, mail submission and delivery, accommodating new systems, security and authentication, and scalability. Experiences with an experimental prototype are reported.<>
