Abstract: An email and message management system invention that rejects all emails and messages unless the messages pass acceptance filter criteria. Without any filtering this invention will refuse to accept all incoming email and messages, whereas current systems accept all email messages without filtering aids. The invention uses several acceptance filtering methods including: a list of acceptable origin message addresses, a list of acceptable origin domain addresses, an algorithm criterion that allows messages based on wildcard type comparisons, a rules method that provides a means to use logic directives, and a method that allows the use of Pass Key Codes to automatically accept messages and to enhance message security. The invention includes an administrative function to set up and maintain the acceptance criteria, provide notification to users of rejected emails, message traffic monitoring for system quality control, and control of a network of the inventions.
