Thunderbird makes e-mailing safer, faster, and easier than ever before with the industry's best implementations of features, such as intelligent spam filters, a built-in RSS reader, and quick search.
Thunderbird gives you a faster, safer, and more productive e-mail experience. Thunderbird was designed to prevent viruses and to stop junk mail so you can get back to reading your mail. Thunderbird provides the most effective tools for detecting junk mail. Our tools analyze your e-mail and identify those that are most likely to be junk. You can automatically have your junk mail deleted or you can put it in a folder you specify, just in case you like reading junk mail. View your e-mail the way you want it. Access your e-mail with Thunderbird's new three-column view. Customize your toolbar, change its look with themes, and use Mail Views to quickly sort through your messages.
Version 1.5 adds a variety of new feature and bug fixes, including spell-checking as you type, integration with server-side spam filtering, message aging, and a built-in phishing detector.
