[Thunderbird 1.0](http://www.mozilla.org/products/thunderbird/ “Thunderbird 1.0) was already released!
In the world of absurdly humongous size webmail service like Gmail, Yahoo! Mail, MSN and others, the need for an e-mail client software is gradually reduced. Not only it need to be installed, which mean you have to own or have your own personal computer, it also need to be configured with some wacky POP3, IMAP and SMTP settings.
But if you still need an e-mail client software other than the highly vulnerable against virus and trojan e-mail client software called Outlook and its little brother Outlook Express, why don’t you try Thunderbird? It’s already out of beta version now. It’s an open source software and the best thing it is free. Go ahead, give it a try.
Eudora and The Bat! are still the choice of hardcore e-mail users but they are not free like Thunderbird. Even though I have to admit that mutt is still the best choice for those hardcore UNIX/Linux users and it is also free.
Anyway, if you want a safe e-mail client software with a good junk filter and other nice feature, give Thunderbird a try, you won’t be dissapointed.
