With great sadness I must now recommend that you uninstall BlueFrog - the most successful anti-spam tool todate. So successful that spammers launched such large attacks upon its infrastructure that ISP where nearly crippled. Read the events that lead to Blue Security's surrender here: http://bluefrogfreaks.blogspot.com/
Blue Frog did not fail - Blue Security did!
Maybe someone could continue the project but instead of having a centralised control network that can be targeted it could use a BitTorrent style peer-to-peer network for deploying commands to the frog.
