For outgoing mail, you will need to use smtpmail.el which allows Emacs to talk directly to SMTP mail servers. This is included with Emacs, and can be set up as follows:
(setq user-full-name "Your full name") (setq user-mail-address "Your@email.address") (setq smtpmail-default-smtp-server "domain.name.of.your.smtp.server") (setq send-mail-command 'smtpmail-send-it) ; For mail-mode (Rmail) (setq message-send-mail-function 'smtpmail-send-it) ; For message-mode (Gnus)
Note that if you want to change the name of the SMTP server after
smtpmail is loaded, then you’ll need to change
smtpmail-smtp-server.
If you are experiencing problems with sending large messages, check
the value of the variable smtpmail-debug-info. If it is
non-nil, you should set it to nil:
