SpamBeagle

SpamBeagle is a spam blocking solution that integrates seamlessly with Outlook. SpamBeagle uses advanced statistical analysis to find spam, while never blocking your real e-mail. SpamBeagle automatically picks up on unique features of your own e-mail to personalize its filtering to you. Spam is impersonal, but your real mail has unique features which competing products ignore. SpamBeagle uses elegant self-configuring Bayesian filtering and fail-safe white/blacklisting. Several layers of spam protection enable you to set the aggressiveness of your filter. Full user-friendly help is built-in if needed.
