And the rc.sendmail(8) under 5.4 stable says that "NONE" is deprecated 
and will be removed in a future release.  According to the man page,

To completely prevent any sendmail(8) daemons from starting, you must set
     the following variables in /etc/rc.conf:

           sendmail_enable="NO"
           sendmail_submit_enable="NO"
           sendmail_outbound_enable="NO"
           sendmail_msp_queue_enable="NO"
