A first embodiment uses an email filter to receive information about an email message from a message transfer agent and then perform limited email pre-processing on the email message. The email filter then stores instructions and data such as the results from the email pre-processing into an internet email header added to the email message. The instructions and data placed into the email header may be encrypted for privacy and security. A later email program may extract the instructions and data from the internet email header and continue the email processing. One disclosed application of the multi-stage email processing system is email authentication."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for securely performing multiple stage email processing with embedded codes","description":"A system and method for performing email processing at multiple stages along an email delivery chain.
