SMTP Service Extension for Secure SMTP over TLS
RFC 2487, “SMTP Service Extension for Secure SMTP over TLS”, is a Proposed Standard document published in January 1999 by P. Hoffman. It has been obsoleted by RFC 3207 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document describes an extension to the SMTP service that allows an SMTP server and client to use 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.
