Abstract
Improved techniques for providing electronic mail services across a network are disclosed. A mail server and its clients communicate through a network. Although the mail server centrally manages the electronic mail services, the clients are able to themselves locally perform certain electronic mail services when the network is unavailable. Accordingly, clients seeking to perform electronic mail services no longer endure significant delays when the network is unavailable. The network can be unavailable for a variety of reasons, including: congestion, out of range, network failure, etc. The network can be wired or wireless. The invention is particularly well suited for networks having sporadic connectivity, high latencies or excessive traffic.
