Abstract

A method, system and computer program product for providing enhanced electronic mail services such as certified electronic mail. The method facilitates a recipient's reconstruction of the initial message, eliminates full resend of the message, minimizes communication during the recovery step, eliminates the need for super encryption, allows the parties to delegate performance to agents (208a, 208n), and provides explicit system enrollments by user certificate authorities (CA's). The system includes a plurality of user sites and a central post office complex (240).
