Mozilla’s Thunderbird email client has finally gone to beta 1 for version 3 of the software, and it looks great. Boasting (at release) full calendar support, threaded emails and a full plugin/addon system similar to Firefox’s famous one Thunderbird 3 is sure to be a hit. And don’t forget its opensource.

This beta release includes

• Tab interface for Mail
• Improvements to IMAP for faster message viewing
• Improved message reader view
• New Add-ons Manager
• Improved Address Book interface
• Improved import of mail from other Mail clients
• Integration with Windows Vista search
• Integration with Mac OS X Address Book
