Mozilla has just released the third beta for Thunderbird 8. Thunderbird is a great email client from the same people who brought you the Firefox browser.
Thunderbird gives you IMAP/POP support, a built-in RSS reader, support for HTML mail, powerful quick search, saved search folders, advanced message filtering, message grouping, labels, return receipts, smart address book LDAP address completion, import tools, and the ability to manage multiple e-mail and newsgroup accounts.
What's New in Beta 3:
- Add-ons installed by third party programs are now disabled by default
Thunderbird makes emailing safer, faster and easier than ever before with the industry's best implementations of features such as intelligent spam filters, a built-in spell checker, extension support, and much more.
