Mozilla Thunderbird is a fully featured, secure and very functional email client and RSS feed reader. It lets you handle mail efficiently and with style, and Thunderbird filters away junk mail too. It offers a pretty and streamlined interface to a very powerful email package. Not only is Thunderbird a secure email client, a sophisticated and very well integrated Bayesian spam filter knocks out most junk mail (after some training). Combine these two aspects of Thunderbird, and you get a sensible feature that automatically sanitizes (potentially dangerous) HTML code and turns off remote images for spam or anything else - worms, viruses - you classify as bad mail. Though not perfect, a scam sensor detects tactics commonly used to fool users. Thunderbird is just as good for good mail as it is against the bad. Flexible views, free-form tags and powerful filters, search and virtual folders (which also work fine with IMAP accounts and across email accounts) make it a snap to handle large amounts of mail. The integrated RSS feed reader extends these abilities to news.

Thunderbird, as a messaging system, is uniquely positioned as the tool that users can use to integrate as many of their communications as they want. By combining an open architecture, a powerful extensibility and customization framework, and a person-centric perspective on communications, Thunderbird is a powerful yet enjoyable tool to help individuals manage their online interactions - whether that's email, instant messaging, social networking messages, or other types of message. Thunderbird will evolve to embrace the Web, by continuing to blur the distinction between what's on the web and what's on the desktop, while keeping in mind the importance of keeping the individual in charge of their online experience.
