IMAP is a protocol used for accessing email messages on a messaging server. The IMAP IDLE command is a widely implemented extension of the IMAP protocol that facilitates real-time email message delivery.
IMAP IDLE allows real-time email message delivery to a BlackBerry device by maintaining a persistent connection between the BlackBerry Internet Service and the email messaging server. Using this persistent connection, the messaging server will notify the BlackBerry Internet Service when new email messages arrive. When the BlackBerry Internet Service is notified by the messaging server that new email messages have arrived, it will connect to the messaging server and retrieve the new email message(s) and deliver them to the BlackBerry device. The benefit of this feature is real-time delivery of IMAP email messages to the BlackBerry device. The impact to the messaging server is low, as IMAP IDLE makes efficient use of messaging server bandwidth.
For more detailed information regarding the IMAP IDLE command, refer to RFC 2177.
