Add JMAP support (as an alternative to IMAP + SMTP)

marclaporte commented 7 years ago

"JMAP is intended to be a new standard for email clients to connect to mail stores. It therefore intends to primarily replace IMAP + SMTP submission. It is also designed to be more generic such that it can be extended with contacts, calendars in the future (replacing CardDAV/CalDAV). It does not replace MTA-to-MTA SMTP transmission."

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 Entreprise 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 used in the code: https://github.com/linagora/openpaas-esn/search?utf8=%E2%9C%93&q=jmap&type=

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." https://blog.fastmail.com/2016/12/22/cyrus-development-and-release-plans/ https://blog.fastmail.com/2016/12/12/why-we-contribute/ https://blog.fastmail.com/2016/12/09/jmap-test-suite/ https://blog.fastmail.com/2015/12/23/the-jmap-momentum-builds/ https://blog.fastmail.com/2015/08/11/an-open-source-jmap-proxy-javascript-library-and-webmail-demo/ https://blog.fastmail.com/2014/12/23/jmap-a-better-way-to-email/

Roundcube Next will support JMAP as well. https://github.com/search?q=org%3Aroundcube-next+jmap&type=Code
