Seeing if I can find it.
I know about blocking the BIS subnets at the FW, but since we have BB users who use Astrasync and Notifylink we would like to avoid blocking everything if possible.
Both AstraSync and Notifylink which works with Exchange 2007\2010 ActiveSync's direct push still goes through BIS network.
