+	The rc.d/sendmail script now uses a heuristic to determine
+	if sendmail should be started at boot time.  It checks the
+	contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
+	owner and mode of the sendmail binary to see if any changes
+	to the mail infrastructure have been made.  If no changes
+	are detected, it will start an SMTP listener.
 
+	Setting sendmail=NO in /etc/rc.conf will override this.
+
+	If you are only using sendmail by default and only for
+	local delivery, it is important that you also update your
+	sendmail.cf so that the SMTP listener only listens on the
+	loopback interface.

 	The safest course is to rm -rf all objects under tools before building.
