~~What the hell is JMAP anyway? Never heard of~~ Another new alternative to IMAP. Can be read here.
Ok, so JMAP is an E-Mail API, replacing proprietary solutions like Gmail's(?). But for what? What does it do/solve?
IMAP is not proprietary. Gmail does support it though, as does pretty much every email provider under the sun. It has limitations though, and JMAP is one proposed alternative to solve some of those.
Note that I don’t have enough knowledge to emit an opinion on whether it’s good or not. I’m just pointing out a couple facts.
People's apparent desire to put JSON into everything? ;)
Unfair. JMAP is a official IETF RFC, a working standard powering a very large mail email service, a modern, open move towards a sort of open ActiveSync.
Fastmail has done a lot of work on this, for free, and no one has a better suggestion, so it’s the state of the art.
Looking into it a bit more, it does seem like a considerable improvement over IMAP and *DAV (especially *DAV). Maybe I was too quick to write it off. Might test it out
It solves a bunch of stuff caused by IMAP being a bit of a mess. Top of the list of JMAP benefits is:
JMAP was developed by the guys that run FastMail (who are the primary developers of the open source email server Cyrus-IMAP). It's easier to implement and more performant.
Side note, Cyrus is a pretty amazing mail server. It doesn't get much love here, but it's bombproof, fast, supports multi-node clusters, IMAP, NNTP, CalDAV, CardDAV and more that I'm forgetting. It's just a bit old school as far as configuring goes.
