>From "man rc.sendmail":

	     (str) If set to ``YES'', run the sendmail(8) daemon at system
	     boot time.  If set to ``NO'', do not run a sendmail(8) daemon to
	     listen for incoming network mail.	This does not preclude a
	     sendmail(8) daemon listening on the SMTP port of the loopback
	     interface.  The ``NONE'' option is deprecated and should not be
	     used.  It will be removed in a future release.

There is additional information in that man page about how to further
tweak sendmail's startup.  Recommended reading.
