SMTP Service Extension for Secure SMTP over Transport Layer Security
RFC 3207, “SMTP Service Extension for Secure SMTP over Transport Layer Security”, is a Proposed Standard document published in February 2002 by P. Hoffman. It obsoletes RFC 2487. It has since been updated by RFC 7817. The canonical text is published by the RFC Editor.
Abstract
This document describes an extension to the SMTP (Simple Mail Transfer Protocol) service that allows an SMTP server and client to use TLS (Transport Layer Security) to provide private, authenticated communication over the Internet. This gives SMTP agents the ability to protect some or all of their communications from eavesdroppers and attackers. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
