Thunderbird is a mail client with spam filters, quick message search, and customizable views.
Supports both IMAP and POP mail protocols, and HTML mail formatting. Import existing email accounts and messages. Built-in RSS capabilities, search, spell check as you type, global inbox, deleting attachments and advanced message filtering round out Thunderbird's feature set.
A software update feature makes it easy to get the latest security and feature updates to Thunderbird. Thunderbird automatically downloads these small updates in the background and prompts you when they are ready to be installed.
