K9 1.28 Product: K9 1.28 Company: KeirNet Website: http://keir.net/ Type: Free Requirements: Windows 98/Me/2000/XP K9 is an email filtering program that works in conjunction with most popular email applications that use the standard POP3 email protocol. Messages pass through K9 on their way to your email program and as K9 processes them it can learn to identify the difference between Spam and Good emails, marking Spam emails so that your email application can file them away or delete them. Initially K9 will not know what is Spam or Good email so you need to correct it when it gets things wrong. Over time you'll find that you have to correct K9 less often as it learns from past mistakes. Eventually you'll only rarely need to correct K9.
