JMAP text/eventsource events #22

Copying comment from #7:

I have contacted fastmail support about their JMAP notification endpoint. Here's part of the help ticket that describes the problem:

epilys writes:

According to rfc8620 the Session object returned by a
JMAP server must contain an eventSourceUrl field that
contains the url...:

" The URL to connect to for push events, as described in
Section 7.3, in URI Template (level 1) format [RFC6570].
The URL
MUST contain variables called "types", "closeafter", and
"ping".
The use of these variables is described in Section 7.3."

[..] Right now I'm connecting to jmap.fastmail.com and the
eventSourceUrl is "https://jmap.fastmail.com/event/" [..]

UPDATE: Fastmail support has replied:

So, it appears push is not implemented yet for our
public JMAP endpoint. I have now created an internal
task for our developers to look into this. I am afraid,
I don't have a timeline on this at the moment, sorry.

I will implement polling until there's a better solution.

just wanted to mention how cool it is you support jmap and even push the fastmail team to do better. Loving meli and looking forward to offline jmap support and all you can add.
