Abstract
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.
