RFC 4405: SMTP Service Extension for Indicating the Responsible Submitter of an E-Mail Message

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

This memo defines an extension to the Simple Mail Transfer Protocol (SMTP) service that allows an SMTP client to specify the responsible submitter of an e-mail message. The responsible submitter is the e-mail address of the entity most recently responsible for introducing a message into the transport stream. This extension helps receiving e-mail servers efficiently determine whether the SMTP client is authorized to transmit mail on behalf of the responsible submitter's domain. This memo defines an Experimental Protocol for the Internet community.
