How is Google Push related to IMAP IDLE? First, "google push" is not a term I often see. I assume you mean "using GCM messages, now called FCM, to cause an app to begin processing", with the usual scheme being that somehow a FCM message is sent from a server via the FCM cloud and to the phone, which causes it to do something like check in with the server. First, this solution is problematic from a privacy perspective (and requires agreeing to some Google TOS), and relies on having google code in the phone. It is, for example, not present in LineageOS. I am not aware of any use of FCM in k-9. (Perhaps that's because I use the f-droid build, where any FCM code would have to be removed in order to produce a Free Software apk. But my I have also not seen any discussion of it.) I am not aware of IETF standards that describe how to integrate IMAP and these sorts of push notification services. There is a generic http push RFC: https://tools.ietf.org/html/rfc8030 and some more or less expired content: https://tools.ietf.org/html/rfc4550 https://datatracker.ietf.org/doc/draft-maes-lemonade-p-imap/ but I am not aware of this being in use in a general/interoperable manner. (It would not surprise me that various proprietary mail services with proprietary companion apps do things like this.) So I will advance the theory that: k-9 does not use FCM/GCM (and hence does not use "google push") IMAP IDLE is the standard approach discussion of "google push"/FCM in this context is without basis and basically a red herring I would be interested to hear any explanations if that's not accurate. -- You received this message because you are subscribed to the Google Groups "K-9 Mail" group.
