Dovecot supports IMAP IDLE as in RFC 2177 (http://tools.ietf.org/html/rfc2177).
I have a few client who has blackberries, iphones and tabs.
Blackberries are using their own proprietary form of push service in conjunction a Blackberry Enterprise Server. None the less they are able to use IMAP IDLE like iPhones and other smartphones or tablet PCs.

which is in the roadmap for dovecot , but not urgent unless there not so many clients using it meanwhile z-push is a good alternative, normally install with apache webserver php on the dovecot server
on android use k9 mail as best imap solution ( no need for z-push etc ) dont know about good alternative imap clients vor iphone or blackberry

No, the LEMONADE profile (RFC 4550) is a set of extensions for IMAP. The focus is on saving bandwith and CPU while working with email on mobile devices and similar limited items. For this it describes how to handle email without the need to completely download it for replying or forwarding. There is nothing about push mail. Howerver IDLE is mentioned as an additionally extension which must be supportet.
If you take a look on the website, you will see the push functionality is only a reference to IMAP IDLE as in RFC 2177.

I don't know about iPhones IMAP client but the default IMAP client for Blackberries is very good -- even better then K9, which I use on my Android.

--snip 'Push' Email (via IMAP-IDLE)
When there is ongoing activity between the client and the server, IMAP will automatically inform the client of the presence of new messages.
The IMAP IDLE command, which is a widely implemented standard extension to the core IMAP protocol and contained within the LEMONADE Profile, ensures that the server will inform the client of new messages even when there is no other activity taking place between client and server.
IDLE maintains the connection by issuing a 'NOOP' command, usually every 15 minutes, to ensure that the connection isn't disrupted by a timeout. The main types of timeouts that usually occur are:
IMAP server timeout: Typically occurs after 30 minutes with no activity.
Underlying TCP connection timeout: Usually after a few hours.
NAT Gateway timeout: Most mobile devices access the Internet througha device operated by the mobile service provider called a NAT (Network Address Translation) gateway. These will typically time out an idle connection after 15 minutes.
NOOP (No Operation) performs no action other than having the server send an 'OK' reply and exchanges a bandwidth efficient few bytes of data.

This is going far off topic, let's take it off list.

I know what you wrote and it still is not correct.
This sounds like my abstract of the LEMONADE profile, just more verbose.
[abstract_(peroration)_of_RFC2177]
This is the reference to IMAP IDLE I talked about earlier.
