RFC 7208: Sender Policy Framework (SPF) for Authorizing Use of Domains in Email, Version 1

Still current, but amended. Parts of this document are changed or extended by RFC 7372, RFC 8553, RFC 8616. Read both.

In plain English — editorial summary, not part of the RFC

Email on the Internet can be forged in a number of ways. In particular, existing protocols place no restriction on what a sending host can use as the "MAIL FROM" of a message or the domain given on the SMTP HELO/EHLO commands. This document describes version 1 of the Sender Policy Framework (SPF) protocol, whereby ADministrative Management Domains (ADMDs) can explicitly authorize the hosts that are allowed to use their domain names, and a receiving host can check such authorization. This document obsoletes RFC 4408.
