Emacs - Gnus

Gnus is the builtin mail client inside Emacs. As long as Emacs is installed, gnus is available.

The bahavior of gnus can be customized in following two files.

• ~/.gnus

  (setq user-full-name "NAME"
        user-mail-address "USERNAME")
  
  (setq gnus-select-method
        '(nnimap "ACCOUNT_NAME" (nnimap-address "IMAP.SERVER.COM")))
  
  (setq gnus-use-full-window nil
        gnus-message-archive-group nil
        gnus-fetch-old-headers t
        nnmail-expiry-wait 'never)
  
  (setq send-mail-function 'smtpmail-send-it
        smtpmail-smtp-server "SMTP.SERVER.COM")
  

• ~/.authinfo

  machine IMAP.SERVER.COM login USERNAME password PASSWORD port imap
  machine SMTP.SERVER.COM login USERNAME password PASSWORD port smtp
  

After the configuration above, gnus can be launched via M-x gnus inside Emacs.
