Re: [Dovecot] IMAP IDLE - iPhone?

Imagine Android default email client. It have no many features, that iPhone's default have (Note: i do not use iPhone, i'm not fan of Apple). Then return to thing I wanna tell in previous letter - the situation, when you really NEED to follow ALL of hundred of mail dirs. I think that battery life is the reason, why this feature is not implemented in iPhone. It will use only one IMAP connection so it is not "it's IMAP limitation" As I told - IMAP limitation is to control only one folder as proven by other devices there is no limitation Can't you distinguish the protocol itself with limitation to follow only one dir and the realization with workaround to create many connections to follow all required dirs? Just imagine that ActiveSync have no that limitation - it use only one connection for any count of mail dirs and therefore it's scalability is very good! how does help me "save battery" if i have a folder-structure maintained by sieve if i do not get my new mails? If you open 10 connections to IMAP server and will IDLE on them - your phone will wake up to reply for ping in every of that 10 connections. Imagine if there will 100 folders? Therefore IMAP really have limitation to use it on mobile devices again: how does it help me if I NEED to check them? Sure! If you NEED to check them - I guess you can find some app in Apple Store. and no, IMAP has no limitations proven by Android-client my Samsung Galaxy S3 has around 25 push folders Yes, it has. The workaround is something else, that limitation itself. no problem with K9 mail to have them in my "common inbox" including my own sent messages while on the desktop i use the folder structure and my battery has a average lifetime of 1.5 days Android's power consumption is a result of very many factors. Spherical 1.5 days is something that have no any sense.

Like mentioned previously in this thread, you can disable the "ping"s in Dovecot. And even when they happen Dovecot makes them happen at the same time. So I think the power usage difference between 1 connection and 100 connections isn't much. I guess, there is no trick, that will change the linear complexity by traffic and by CPU usage. If you can change settings in dovecot - you can set up ActiveSync there. It's more suitable for mobile mailing.

I'd like to configure our iPhones at work to go directly to my dovecot server (currently dovecot-2.0.9-2.el6_1.1.x86_64). Using the IMAP IDLE (push email) protocol. Has anyone successfully deployed this? If yes, did you have to use an app from the Apple store? For me the IMAP process works, however it's clearly not notifying the client when new email is detected on the server. cya Craig iPhone will not notify for new mail in any folder, except INBOX - it's IMAP limitation. IMAP IDLE monitor only one selected folder. If you need notifying of new mail in copule of mail folders you shold look for ActiveSync realization.
