Overview — AboutBlackBerr y and the BlackBerry Enterprise Server

The BlackBerry Enterprise Server runs as a Lotus DominoServer
task that can monitor many users at once over a single
administrative connection to the Lotus Domino server. The
BlackBerryEnterprise Server maintains a direct TCP/IP connection
(ServerRouting Protocol or SRP) to the wireless network. This mode
ofconnection requires that you configure your corporate firewall to
allow the BlackBerry Enterprise Server to connect through port
3101. This is not a “hole” in the firewall, since only an outbound-
initiatedconnection is required.
Figure 1 shows an example of events that occur when an external
emailmessage is sent to a user on the BlackBerry Enterprise Server.
