Email is the most prevalent form of business information exchange. It is used as an interpersonal communication tool and often as a default choice to send files. Despite the importance of the email system, the whole ecosystem relies on 50-year-old architecture and protocol design.

The revised Internet Mail architecture uses a unique way of organizing data communication by introducing a new type of mailbox called a resource mailbox. Separating the resource mailbox from the email address allows digital resources such as messages, documents, images, videos, and audio to be exchanged securely and efficiently. Moreover, this architecture offers better protection against unwanted emails and helps to keep your emails safe and private. Many industry sectors can benefit from using this architecture. For instance, physicians can exchange X-rays, CT scans, or MRI scans with other physicians for expert advice.

As a proof of concept, I have been working on Cargomail—an open-source reference implementation of the revised Internet Mail architecture. The Cargomail white paper describes many other advancements in utilizing this new concept. The document is intended to convey both the "big picture" and some technical details.
