Implementing Microsoft ForeFront Security for Exchange

I have Exchange 2007 SP1 with the recent update rollup 5 installed. I tried to install Forefront with SP1 and it breaks my exchange. When I send an email, the server accepts it, but goes no where. Same thing with sending email from the outside to it, it accepts it but does not go to internal users. It seems that all email is stuck in Forefront. Because when I uninstall Forefront, everything works again. Does forefront require major configuration to work with exchange or is it supposed to work out of the box?
