摘要：Many electronic mail systems are now available. Interconnecting these largely independent systems broadens the communities of users that can communicate electronically. When the systems are at different sites, the existing style of loose interconnection is sufficient. But when a local site has multiple mail systems, a user cannot easily perform tasks such as reading mail from all the systems during a single session. An integrated local mail environment that lets a user perform such tasks easily desirable.Such an integrated environment should have three properties. First, it should be inexpensive to implement the environment. Replacing the existing mail systems with a single, new system is too expensive. Second, it should be inexpensive to integrate a new mail system into the environment. As new systems are acquired, it should be easy to use their mail services effectively. Third, it should be possible to integrate diverse classes of mail systems into the environment. We have designed and implemented research on Heterogeneous Mail System as an environment with exactly these properties.
