This behaviour is pretty common, not just Mail.ru – instead of building actual IMAP and MIME capability into a phone app, client developers push all IMAP connection handling and MIME processing to their servers and expose HTTP based API to the mobile client. This way the app developers can build UI/UX stuff and ignore email protocol complexity, it also allows to use native push channels more easily. Downside obviously is that all email is going through a 3rd party provider but considering how widely this technique is used, not many seem care about it.
