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. Learn more.
