Spam Sleuth has analyzers, and each analyzer: Friends, Spammers,To, Goodwords, Badwords, Profanity, Subject, Attachments, Charsets, HTML Volume, etc. looks at an e- mail a different way and assigns points. The more points an e-mail message receives the more likely it is to be deemed as spam. The less points an e-mail message receives the more likely it is a real gem. Think of it as though it was a contest, and each Analyzer is a different judge, and the messages are the contestants, and Spam Sleuth is the scorekeeper. Every judge looks at the e-mail message and assigns points based on specific criteria. Then all of the points are added together to create an overall total. More points is bad, and less points is good. As the administrator you can make up a standard configuration that your employees can add/change depending on how much permission rights you give them.
