Overview

Thunderbird is Mozilla's long-lived email client, now undergoing a renaissance with the Supernova redesign. It supports IMAP, POP3, SMTP, and multiple accounts. Built-in OpenPGP lets you encrypt email without installing plugins.

On Linux it integrates with GNOME and KDE calendaring via CalDAV. The extension ecosystem adds spam filtering, news feeds, and more.
