JMAP: Modern Mail Standard

How do various mail clients talk to their respective backends? I.e. what does iOS Mail use to talk to iCloud? The GMail iOS app speaks a bespoke binary protocol to Google's servers, not IMAP.

iCloud mail in iOS uses plain IMAP. The synchronization stack for iCloud is surprisingly based on open standards: IMAP, CalDAV and CardDAV.
