Mozilla Thunderbird is a popular free, cross-platform e-mail, RSS and newsgroup client.
Mozilla Thunderbird is packed with great features such as IMAP/POP and HTML mail support, 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.
Mozilla Thunderbird includes a fully-integrated Usenet newsgroup reader supporting all the basic functions, such as subscribing to newsgroups, downloading headers and messages, offline support and thread watching/ignoring.
It provides enterprise and government grade security features such as S/MIME, digital signing, message encryption, support for certificates and security devices. There are a large number of add-ons which extend the functionality of Thunderbird.
Thunderbird can be used to access websites that make content available through RSS feeds. Unlike Firefox, however, which gives you access to RSS feeds through Live Bookmarks, Thunderbird lets you view RSS content in a way that is very similar to reading email: the RSS feeds that you subscribe to will be listed in the folders pane, the individual article titles or “headlines” will be displayed in the message-list pane, and when you click on a title the article content will be displayed in the message preview pane.
It has won a number of awards.
