Bluecase Anti-Spam plugs right into your email application. It uses 4 powerful engines to quickly and accurately check every piece of mail coming into your inbox. Unlike other applications that simply compare email against a community blacklist, Bluecase Anti-Spam looks at the source of the email, its content and characteristics, and even check for tricks that identify it as spam.

Bluecase Anti-spam integrates seemlessly into Outlook without the need to do extensive setup. Configurable options allow you to fine tune control and training of the program, including filter strength, treatment of messages identified as spam, blocking of I.P. addresses and countries you define, use of public blacklists, and Bayesian word training.

The bottom line with this application is it's fast and it's effective. That's what you really need in an anti-spam application - something that installs itself and you don't have to think about much again. Full subscription includes Scam Siren Anti-Phishing toolbar.
