K9

intelligent anti-spam filtering

Our Rating: (Very Good)

K9 is an anti-spam email filtering application that works in conjunction with your regular POP3 email program and automatically classifies incoming emails as spam (junk email) or non-spam. The program uses intelligent statistical analysis that can result in extremely high accuracy over time and eliminates the need for maintaining dozens of rules or constant updates to be downloaded. K9 learns from what you are considering spam and will automatically tag all future emails that match the pattern. You can then set up rules (in Outlook or Outlook Express etc.) to delete or move the spam-tagged messages. The initial results will be moderate, however, after processing a few dozen emails, K9 will detect a very large percentage of the spam and further improve accuracy over time. The advantage of this is that the program is able to filter spam based on your personal email statistics, rather than a generic or global list. The interface allows you to view your mail history and change the status for certain messages, thereby automatically updating the filter settings. Additional features include whitelist and blacklist, long-term statistics and more. K9 does not delete any messages automatically , but only tags them for further processing. A very accurate and highly customizable spam filtering method, that does however require some familiarity with email accounts.
