Gnus
What Gnus is
Gnus is a free message reader that runs under GNU Emacs and handles both news and mail. It can draw groups from web-based sources, read news through NNTP servers or a local spool, and retrieve mail through IMAP or POP3, including documented SSL/TLS and StartTLS options. RSS subscriptions are supported, with OPML import and export. The program is fully MIME-compliant and follows the message character sets supported by GNU Emacs. Its stated purpose is an efficient, extensible way to manage large numbers of messages from varied sources and forms. Gnus also supports offline access, scheduled sending, and calendar tools. Documentation covers signing and encrypting messages and measures for thwarting spam. Stable versions are included with Emacs and XEmacs. Desktop coverage includes Linux, macOS, and Windows, while development builds are available through the Emacs Bazaar and Gnus Git repositories.
