Type your message and send it off with ctrl-c ctrl-c. By default message mode will use your /usr/sbin/sendmail command to send a mail, so make sure that works.
One annoying standard configuration of message mode is that it will hide the sent mail in your emacs frame stack, but it will not close it. If you type several mails in an emacs session they will accumulate and make switching between buffers more annoying. You can avoid that behavior by adding `(setq message-kill-buffer-on-exit t)` in your .emacs file which will really close the mail window after sending it.
