Cloudmark Desktop for Thunderbird is a fully automatic anti-spam and anti-phishing add-on for Mozilla Thunderbird that filters your email as it arrives in your Inbox, and moves suspected spam into a designated spam folder, from where you can review it later or delete it. The filtering mechanism is based on the Cloudmark service, the largest community-based platform used to stop the plague of junk email and email fraud, and it does not require you to create any filters or rules on your own. You can however create a white list, to make sure certain contacts will never be filtered, and also re-classify selected messages.
