Spam Site Smasher is an e-mail filter that avoids the use of keywords. Instead it detects spam messages based on the web sites they contain. These addresses can't be hidden or misspelt because the spammers needs you to click on them. This makes the program very simple to use as you need only tick the web sites you don't won't messages from. Messages from friends and family will always get through as they won't contain links to banned sites.
