>As you say, IMAP could do with modernisation In theory that's doable. In practice modernizing a protocol with extensions is though, since support ends up patchy. Especially when the big email providers have few reasons to make a documented, non-propriety extension. Why would they when they can instead push people to their propriety apps? It's definitely possible that JMAP doesn't catch on. In that case, we'll probably just keep languishing with non-modernised IMAP. The key is getting client support, especially in mobile (where there is a noticeable user benefit) and in open source software.
