__Add support for JMAP (JSON Meta Application Protocol), as an alternative to
IMAP + SMTP__

"JMAP is a modern standard for email clients to connect to mail stores. It
therefore primarily replaces IMAP + SMTP submission. It does not replace
MTA-to-MTA SMTP transmission. JMAP was built by the community, and continues to
improve via the IETF standardization process. Upcoming work includes adding
contacts and calendars (replacing CardDAV/CalDAV)."

You may wonder "Who uses or supports it?"

Cyrus IMAP and Apache James are the notable ones here:  
http://jmap.io/software.html

OpenPaaS is an open source Enterprise Social Platform which is led by LINAGORA
(which has more than 150 employees)
https://linagora.com/
http://www.open-paas.org

OpenPaaS is using Apache James. And you can see JMAP commits:

https://github.com/apache/james-project/search?q=jmap&type=Commits

In this video: https://www.youtube.com/watch?v=2QZIi3EO6rQ , Benoit Tellier
explains why they decided to invest in James and JMAP (among other things).
LINAGORA has 5 full time employees which are devoted to the project.

FastMail started this initiative: "JMAP is FastMail's protocol with the warts
removed. We leverage existing standards like HTTP, JSON, and native push
channels on platforms which have them - making it easy for developers to work
with."
Here are blog posts from when the project started, which contain a lot of
information on the motivations, the goals and the process:

Cyrus IMAP is an email, contacts and calendar server, and has heavily worked to
add JMAP support:

atmail explains the many benefits:
https://www.atmail.com/blog/how-does-jmap-make-email-better/

The are two libs in JavaScript:
https://github.com/jmapio/jmap-js
https://github.com/linagora/jmap-client

and we recently started a PHP lib because the WikiSuite project is committed to
JMAP:
https://github.com/WikiSuite/zend-jmap
http://wikisuite.org/JMAP

The "JMAP Proxy implemented in Perl" is coming along nicely:
https://github.com/jmapio/jmap-perl/commits/master
This permits to serve JMAP from a traditional IMAP server.

The "JMAP test suite" is also actively developed:
https://github.com/fastmail/JMAP-TestSuite/commits/master

We worked on these last three at the recent hackathon:
http://wikisuite.org/July-2018-JMAP-IETF-Hackathon-in-Montreal

I witnessed the team work at this hackathon, and the previous one in London.
And on the mailing list. The core JMAP team is working in a smart and inclusive
way to make JMAP awesome and a success now and for the decades to come!

Thanks!

P.S. I use Claws Mail because it's the only desktop mail client (Free / Libre /
Open Source or otherwise) I have found that can deal with the email volume I
have. Adding JMAP support would make it even more efficient.
