I want to install Blackberry Express Server on my Exchange 2010 server for users at my company, but I am wary of simply opening up ports to my server directly to the internet.
Are there any good ways to ensure that inbound traffic is blackberry-only and safe? I know Blackberry does allow a seperate server to be installed in the DMZ, although that would really be overkill for my organization.
This is a blackberry article about the firewall requirements: http://www.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalId=KB03735
