Using the existing RFCs for email address definitions as approved by the IETF, ZO extends the basic mechanics to allow mail servers to negotiate unique email addresses on their clients' behalves on a per-service basis. These extensions eliminate 100% of unregistered email content and 99.9999% of spam emails while costing no money to the mail service providers or their mail clients.

Piggybacking on existing root-of-trust and digital certificate principles, ZO augments the existing model by enabling a second verification mechanism that is not dependent on the primary root certificate authorities as recognized by Apple, Microsoft, Android, Firefox, Chrome, etc. and which is impervious to nation-state cyberattacks and government influences.
