Smartest Way to Stop Junk Mail

Mozilla Thunderbird removes spam and helps keep your Inbox clean.

Tired of spam and annoying advertising in your Inbox? Mozilla 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 have your junk mail automatically deleted or put in a specific folder.

To activate the Junk Mail filters, go to Tools > Junk Mail Controls..., click the Adaptive Filters tab and check the Enable adaptive junk mail detection option.

Mail, the Way You Want It

We've added a new three-column view to access your e-mail.

View your e-mail the way you want it. Choose between three unique message views. Select your toolbar layout. Customize your toolbar buttons, and use Mail Views to quickly sort through your e-mail.

In the end, all these possibilities make you more productive and efficient, which is what Mozilla Thunderbird is all about.

Built-in Spell Checking

The intelligent spell checker keeps your mail professional.

There's no need for third party spell checking software. Mozilla Thunderbird comes with an integrated spell checker developed by the Spellchecker Mozdev Project. All you need to do is to click on the Spell button in the toolbar, and Mozilla Thunderbird will do the work for you.

Safe and Secure

Mozilla Thunderbird provides enterprise and government grade security features such as S/MIME, digital signing, message encryption, support for certificates and security devices.

Unlike many other products, Mozilla Thunderbird doesn't allow scripts to run by default. This results in a more secure product than other mail clients on the market and helps stop the spreading of worms and viruses on the Web.

Unlimited Functionality through Extensions

How powerful do you want your mail client? You decide!

Mozilla Thunderbird is already packed with great features like IMAP/POP support, support for HTML mail, labels, quick search, a smart address book, return receipts, advanced message filtering, LDAP address completion, import tools, powerful search, and the ability to manage multiple e-mail and newsgroup accounts.

In addition to this, Mozilla Thunderbird lets you add additional features as you need them through extensions. Extensions are powerful tools to help you build a mail client that meets your specific needs. Take a look at the various extensions available.

Integrated News Reader

Mozilla Thunderbird is not just a mail client, it also includes a fully-integrated Usenet newsgroup reader! It supports all the basic functions, such as subscribing to your favorite newsgroups, downloading headers and messages, offline support and thread watching/ignoring.

Personalize with Themes

Just about any part of the interface can be changed with themes.

With themes, you can change the look and feel of Mozilla Thunderbird. A theme can simply change the toolbar icons or it can change every piece of the application appearance. You can download and install themes with just a few clicks.

Windows, Linux or Macintosh? Regardless of your choice of operating system, Mozilla Thunderbird is available for you. It currently runs on Windows 95, 98, Me, 2000 and XP, as well as Linux, Mac OS X, OS/2 and Solaris.
