SMTP Submission Service Extension for Future Message Release
RFC 4865, “SMTP Submission Service Extension for Future Message Release”, is a Proposed Standard document published in May 2007 by G. White, G. Vaudreuil. It updates RFC 3463, RFC 3464. The canonical text is published by the RFC Editor.
Abstract
This memo defines an extension to the SMTP submission protocol for a client to indicate a future time for the message to be released for delivery. This extension permits a client to use server-based storage for a message that should be held in queue until an appointed time in the future. This is useful for clients which do not have local storage or are otherwise unable to release a message for delivery at an appointed time. [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.
