JMAP-Mail specifies a data model for synchronising email data
with a server using the core protocol defined in
JMAP-Mail is the first user of the generic mechanism described
in the core protocol.
Working Group Summary
The initial proposal for JMAP-Mail included a special "Outbox"
folder for sending mail. This has been changed to use a new
object called "EmailSubmission" instead - which has been tested
and is in use at FastMail.
The working group also rewroked the data model considerably.
This data model includes a simplified set of views into the full
MIME data structure to allow easier client development, while
still giving the full power of the stucture where required.
This work has been done concurrently with the EXTRA working group
which is extending RFC3501 (IMAP4), with an eye to keeping both
email access protocols compatible with each other.
The only known implementations of the latest protocol have been
done by FastMail staff, but there exist multiple implementations
of earlier drafts, and their authors have read the current
drafts - they're just waiting until publication to update to the
latest version. Both client and server implementations are
available as open-source.
The JMAP working group is small, but there have been multiple
people who have read the document carefully - Chris Newman who
is now listed as an author gave particularly detailed reviews.
The authors of the various parts of the FastMail stack that are
now implemented on this spec, and of the two test suites covering
the spec, have also found multiple issues in the last 6 months
which have fed back into the final document.
Multiple email server vendors have indicated their intention to
either add JMAP to their existing servers, or to build new
services on top of the JMAP data model.
The Document Shepherd is Bron Gondwana and the Responsible
Area Director is Alexey Melnikov.
(3) The document has had a complete read through of version 10 by the
Document Shepherd, which led to a handful of clarification questions
that made it into verison 11. I have also implemented most of it and
reviewed code from others implementing other parts.
(4) With a document of this size, there's always a possibility that we
missed something important, but multiple reviewers with long-term experience
in these kinds of protocols have been over the documents, including nit-picky
test writers. I'm confident that it's implementable as specified.
(5) The main review has come from the EXTRA working group, which has
many members in common. There has also been review from security
experts who suggested possible risks and mitigations.
(6) The Area Director has been heavily involved in the working group,
there are no specific concerns with the document that I'm aware of.
(7) Yes, each author listed at any point on both the current and earlier
drafts has been contacted and confirmed that they have no disclosures.
(8) There have been no IPR disclosures filed.
(9) The working group is small, but everyone has spoken. There's have been
no objections to any of the recent changes, and there's full consensus of
(10) Nobody has threatened any appeals or objections.
(11) IDnits found references to non-RFC2606-compliant FQDNs, which are
inline references to URLs that currently exist, perhaps they should be
moved to references, but I'm not sure the policy on that. It also doesn't
directly mention the RFC5788 update in the abstract. The are also text
(12) There are no formal review areas required.
(13) All references within this document been identified as
either normative or informative.
(14) There is a normative reference to draft-ietf-jmap-core which will
require publication before this document.
(15) There are no downward normative references references.
(16) Publication of this document will update RFC5788 by renaming
the IANA registry created in that document, and also adding an extra
column to the registry detailing the use for each entry.
(17) The IANA considerations sections requests that the registry
from RFC5788 be altered, and also specifies some new entries and
the changes to be made for all existing entries.
This document also extends the registry defined in
draft-ietf-jmap-core with additional entries.
(18) There are no changes required to expert review in this document.
(19) The formal sections are JSON. One of the authors recently
tested all the examples in the document to be parseable, and
most have been copied directly from network dumps out of
working systems using the protocol.
