Thunderbird is a free, open-source, cross-platform application for managing email and news feeds. It is a local (rather than a web-based) email application that is powerful yet easy-to-use. Thunderbird is developed, tested, translated and supported by the folks at Mozilla Corporation and by a group of dedicated volunteers. Thunderbird gives you control and ownership over your email. There are lots of add-ons available for Thunderbird that enable you to extend and customize your email experience.
It is a sophisticated and very well integrated Bayesian spam filter knocks out most junk mail (after some training). Combine these two aspects, and you get a sensible feature that automatically sanitizes (potentially dangerous) HTML code. Also turns off remote images for spam or anything else you classify as bad mail. For example, the worms and viruses. Though not perfect, a scam sensor detects tactics commonly used to fool users.
Flexible views, free-form tags and powerful filters, search and virtual folders make it a snap to handle large amounts of mail. Also work fine with IMAP accounts and across email accounts. 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. It 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 combines an open architecture, a powerful extensibility and customization framework. Also a person-centric perspective on communications.
