I just wanted to let people know about a great freeware program I recently found that filters out spam. It uses something called a Baysian filter which learns as you teach it what is spam and what isn't. It is currently filtering out about 92% of the spam I get and that number is gradually improving as I correct the program. It works with email clients like outlook and outlook express, but not with internet based email like yahoo, hotmail, etc. The program is called K9 and full description etc. is here

Highly recommended if spam is a problem for you.
