Mozilla Thunderbird 3 is a free Web mail handler, a strong desktop client with superior speed and responsiveness time.
The basic features remain: junk mail filters, HTML support, multiple accounts, POP, IMAP, and Microsoft Exchange server support. Security features include S/MIME, digital signing, message encryption, and a built-in phishing detector.
New features include a new activity manager, a new Gmail-like e-mail archive functions, improved Growl notifications, and more keyboard shortcuts. The search tool integrates results with Spotlight desktop searches, along with Growl notifications and integration with the OS X address book.
Another improvement is the tabbed user interface: double-clicking a message opens it in a new tab. Plus Thunderbird will re-open the same tabs that were previously opened when closing and then restarting the program.

It turned out to be very comfortable to use. One more pleasant thing about the application is the fact that it's free. The tab feature really makes dealing with letters comfortable.
Totally awesome email application, and it's completely free on top of everything!!
It would appear the major version number jump is due to the fact that Thunderbird now based on the Mozilla Gecko 6 engine
