    Yahoo mail (which includes Rogers email accounts) was never a 'push' based email on BB10. For some reason, BlackBerry couldn't figure it out or didn't care to figure it out. My iPads have no problem with 'push' on my Rogers accounts.

    Now with Android on the Priv, how does Yahoo mail / Rogers mail work? Is it push?

    Yahoo's IMAP implementation is broken. The problem with push email is that it requires keeping a TCP channel open; this is true for Exchange as well, by the way. IMAP uses a protocol feature called "IDLE" to do this; you issue an IDLE command with the folder to monitor (in this case the Inbox) and then the other end notifies you when a new message arrives. The client can then issue a new messages command and proceed to retrieve whatever piece of them (whole message, headers only, etc) it wishes.

    But keeping that channel open requires resource on the server end, and Yahoo cheats by dropping that connection "silently" in a way that the other end doesn't detect right away (or it would re-establish the link!)

    This cannot be done via a connectionless protocol such as UDP, incidentally, because essentially all mobile devices are behind NAT (address translation) at the service provider end and as a result there is no way for a connectionless notification to reach the handset. The same problem exists with floating-address home broadband where the router provides the NAT service.

    It's not the phone that's the problem, it's the server and decisions made at that end.

    Tickerguy is correct. Even in Android Yahoo is not push based. The only work around is to link your Gmail to Yahoo mail. Gmail queries Yahoo at set intervals & returns the results to your phone thru Gmail. It's not exactly push, but it's faster than stock Yahoo mail

    That's why I dumped my personal. Yahoo email addresses to Outlook and Gmail. Over 3 years ago
