Spamfighter

If you are looking for an Outlook, Outlook Express, Windows Mail or Mozilla Thunderbird spam filter to remove spam and phishing e-mails from your Inbox, Spamfighter is the spam filter you are looking for. Spamfighter is using the power of 6 million people that instantly report if they receive a spam mail. When several people have reported the same spam mail, it's automatically blocked for the rest of the Spamfighters. In this way very few people will ever see the spam mail. On top of that a lot of spam is filtered before it ever hits the community by the spam filter. Spamfighter is available in English, German, Spanish, Chinese, French, Italian, Greek, Dutch, Swedish, Norwegian, Suomi, Japanese, Portuguese, Bulgarian, Russian, Thai, Vietnamese, Czech, and Danish.
