[Dovecot] IMAP IDLE - iPhone?

[dovecot at noboost.org]

Hi All,

Probably a very common question now days.
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
