A direct access server is operative with the network engine for polling electronic mailboxes of users from an email source and retrieving electronic messages from the electronic mailboxes and pushing any electronic mailboxes to the network engine to selected users subscribed mobile wireless communications devices. The direct access server communicates with an email source using the internet message access protocol (IMAP) and IMAP-Idle supportable connections to accept real-time notifications such that when a connection limit is reached or exceeded to an email source, the direct access server disables IMAP-Idle connections to the email source.
