Abstract: Information common to multiple e-mail messages (called common content "chunks") is separated from the individual e-mail messages before transmission. The chunks are then transmitted separately from the individual e-mail message information, and reassembled into a complete e-mail message at the receiving site.

Abstract: A high volume e-mail "newspaper" delivery system contains, for each customer, a personal configuration file containing the information resources that the customer would like e-mailed to his desktop. The configuration file is highly customizable, allowing the end-user detailed control over the content, format, and timing of the delivered e-mails. The e-mail messages to be sent are hashed to multiple, parallel transmission queues based on their destination MX hosts. This arrangement of transmission queues significantly increases total e-mail output because multiple queues are simultaneously processing the e-mail transmissions. A unique job number is appended to each e-mail message as it is created. The job number is used by the system to identify and track the e-mail message through the system before it is transmitted, and if the message bounces, when it returns to the system.

Abstract: An automated system of passively distributing personalized, unique information to users via electronic mail or facsimile. The system formats information into messages conforming to electronic mail protocols and transmits these messages to the user's electronic mailbox or reception system. The system also allows a user to automatically edit an underlying information database via electronic mail to modify services and further allows third parties to insert text messages into outbound message(s).
