SpamFighter is a community based spam filter system. It works by not only filtering spam according to what you mark as as spam, but also the emails the entire community as a whole flags as being spam. This means you don’t have to spend time training your spam filtering software before it can actually filter out spam properly for you.

Using SpamFighter

SpamFigter seamlessly integrates into Microsoft’s Outlook. Once you have installed it, a small SpamFighter icon appears in Outlook, letting you know that it’s started working.

Free and Paid Versions

The creators of SpamFighter had a very clever strategy. They made a light weight version of their spam filtering software and made it free. As an added bonus they collect all the spam information from millions of users, and can make their pair for spam filter, really great. It’s a clever strategy, and in the end it means every wins to some degree.

Performance

As you can expect, SpamFighter works very well and the great thing is that it works right away. It has a very high accuracy. It doesn’t often misclassify an email as either spam, or not spam.

Conclusions

All in all SpamFighter is a great product that’s also backed by a great idea of involving an entire community into the spam filtering fight. Personally I’d prefer the whole project if it were run by a non profit group, but that may be asking a bit much.

Clearly the biggest flaw with SpamFighter is that it only works with a single email client – being Outlook.

Despite these disadvantages, as a whole I have to recommend SpamFighter, it gives some of the best spam filtering results available, and it is after all, free.
