This stands for BlackBerry Enterprise Server. BES turns a BlackBerry into a powerful government-quality secure email system with full wireless email and PIM synchronization, including email folder structure, moves between foldres, deletitions, unread/read indicators, etc. An administrator can even kill a BlackBerry remotely through BES when it gets stolen too. People who need inexpensive BES, can see the Hosted BES FAQ. BES also provides MDS capability, which is generally higher-reliability than the recently available TCP/IP stack found on BlackBerries."

My guess is that you have it.
The quickest way that I know to test it is:
-open an e-mail you sent from your Blackberry
-Scroll up. it will either say, "Using: Desktop (Secure)" (means BES) or "Using: Web Client" (means no BES)
another test would be
-Go into Options off of main screen
-click Message Services
-It will say "Messaging (CMIME): ______" either Web Client or Desktop (see above for which is which)
if you hit your trackwheel and "change option"...if it allows you to select either Web Client or Desktop...you are hooked up with both (or can be...just have to set-up Webclient)
