Apart from the availability and accessibility, confidentiality, message integrity, and authenticity are primary requirements expected from an email system. However, these features are now incorporated into email systems since the introduction of public key cryptography. The world is on its way. Now, email becoming crucial for most e-commerce transactions. But, still there are some features missing from the email systems which should be incorporated in order to make this system much more perfect. Guaranteed delivery, some control over an email after send, and proofs for posting and opening for an email, are some of them. This document describes and explains how a successful attempt has been taken to achieve this requirement, by developing a proxy for email, or as referenced in the overall context, a Notarization Authority. Also, this document describes the concept of time-stamp, and a special certificate derived from it for used as proof of time posting and opening for email. Major concerns are taken in order to preserve the efficiency and effectiveness at a higher degree." -Extracted from the Project Report Deliverables:
