Brilliant stuff, but kind of sad that this hasn't caught on already. I realize that standardization has only firmed up recently, but other standards like HTTP and TLS see preview releases supported in major products well before they are finalized.

Who uses JMAP besides FastMail?

Isn't email mostly consolidated to a handful of providers with published APIs? (Office365, Google, Yahoo) I'd be curious to see the market share of just those 3 combined.

And they don't have any incentive to move to this.

Perhaps for individuals and small businesses, but certainly not for large organizations, many of whom are running their own Exchange (or whatever else) servers.

Imagine if some company offered a $5/month service that connects to o365/gmail/yahoo via imap, and then presents your email via jmap. After a few years of that company making money, I could see at least one of the big 3 offering a $1/month option to cut out the middleman. And if more of them start offering the same, then it's only a matter of time before one of them offers up jmap for free.

Unlikely, but seems plausible to me.

Don't need to undercut the middleman's pricing to be worth cutting a point of failure. Could even charge more and still attract users that never would have purchased it from the middleman.

That sounds a lot like Fastmail to me!

Looks like there are some open source mail server projects that support it: https://jmap.io/software.html
