Need some info.... - Pron filters

[Kingpin]

I was wondering if there is an email program that can filter out any porn or allow me to filter it. outlook Express at this time does not allow me to do this. Is there some sort of anti-porn program I can "get" my hands on. Any and all help would be greatly appreciated.

I need this because Snuka keeps sending my kids naked pics of himself. We all know that is GOD damn scary. Thanks
