Thunderbird

Mozilla Thunderbird is a free open source desktop email client that was first released in December 2004. The client nowadays includes email management options but also options to connect to newsgroups, subscribe to news feeds and use various chat protocols so that is is commonly referred as a messaging client nowadays.

Thunderbird manages each email address that you add in accounts, and provides you with a wizard that walks you through the setup process. The developers have added wizards for several popular email services such as Gmail, Hotmail and other online mail services to the client to make setup as easy as possible. For those services, only the email address and password are required to complete the setup.

It furthermore includes a junk filter, an extension system that is identical to the system that the Firefox web browser uses, and various o

Mozilla recently decided to lower the priority of Thunderbird development. While this does not mean the end of the client, it means that development will chuck along at a slower pace.
