Technical Summary JMAP-Mail specifies a data model for synchronising email data with a server using the core protocol defined in draft-ietf-jmap-core. 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 reworked 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 structure 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. Document Quality 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.
