Technical Summary

   This document is a specification of the basic protocol for Internet
   electronic mail transport.  It (including text carried forward from
   RFC 5321) consolidates, updates, and clarifies several previous
   documents, making all or parts of most of them obsolete.  It covers
   the SMTP extension mechanisms and best practices for the contemporary
   Internet, but does not provide details about particular extensions.
   The document also provides information about use of SMTP for other
   than strict mail transport and delivery.  This document replaces RFC
   5321, the earlier version with the same title, and supersedes RFCs
   1846, 7504, and 7505, incorporating all the relevant information in
   them.

Working Group Summary

   The EMAILCORE working group’s charter was to perform a "limited review and
   revision" of documents that describe a widely installed and used protocol.
   Participation in the working group was generally limited to a
   dozen or so individuals, owing in large part to the group’s work being
   focused on revising fifteen year old documents that are themselves
   fourth-generation revisions of originals first published in 1982.

   When reviewing this document, it is strongly suggested that you refer to:
   https://author-tools.ietf.org/iddiff?url1=rfc5321&url2=draft-ietf-emailcore-rfc5321bis

   Progress through the WG was sometimes slow and occasionally contentious,
   but consensus was reached on all such issues.  The document is ready to proceed.

   There is a fair amount of leftover editorial material in the form of comments
   that will be deleted before publication, to provide reviewers with background that
   may be useful prior to preparing the to-be-published version.

Document Quality

   SMTP is ubiquitous.  There are intentionally no breaking changes to the
   deployed base; this document refines and clarifies a number of things and
   resolves errata, finally advancing SMTP to full standard.

   No reviews are required that have not already been scheduled
   and completed.

Personnel

   The Document Shepherd for this document is Alexey Melnikov. The
   Responsible Area Director is Murray Kucherawy.
