The system may further include at least one email aggregation server for polling the mailboxes for email messages, and forwarding the email messages to respective mobile wireless communications devices. The at least one email aggregation server may divide each of a plurality of repeating polling time intervals into a plurality of subintervals, and schedule each mailbox for at least a first type polling over each subinterval and for a second type polling over each polling time interval. The second type polling may be more comprehensive than the first type polling.
