 Rather than providing a Push e-mail mechanism, The Lemonade Profile relies on the existing IMAP capability to provide short notification messages at any time, and includes support for the IDLE command.When there is ongoing activity between the server and the client, IMAP will automatically inform the client of the presence of new messages.IDLE ensures that the server will inform the client of new messages even when there is no other activity taking place between client and server by ensuring that the connection is not disrupted by a timeout.
