5.3-Beta7: sendmail script bug?

Hello,

When no sendmail program is running, do:

# cd /etc/rc.d
# ./sendmail start
Starting sendmail.
554 5.3.5 /etc/mail/sendmail.cf: line 279: Unknown address family inet6 in Family=option
# ls /var/run/sendmail.pid
ls: /var/run/sendmail.pid: No such file or directory
# ./sendmail stop
sendmail not running? (check /var/run/sendmail.pid).
# ps awux | grep sendmail
smmsp 881 0.0  8.4 3320 2356  ?? Is 2:44AM 0:00.02 sendmail: Queue runner_at_00:30:00
           for /var/spool/clientmqueue (sendmail


(I have disabled IPv6 support for kernel and world)

Apparently sendmail keeps running, even after being stopped.
Moreover, the sendmail script does not create a /var/run/sendmail.pid.

Is this a bug?

Rob.
