I found this:

# cat /etc/cron.hourly/check_MailScanner
#!/bin/bash

LOCKFILE=/var/lock/check_Mailscanner.lock
MS_LOCKFILE=/var/lock/subsys/MailScanner.off

if [ -f $MS_LOCKFILE ]; then
  echo "MailScanner manually shut down (no
$MS_LOCKFILE file)."
  echo "Not restarting."
  exit
fi

# the lockfile is not meant to be perfect, it's just
in case the
# two makewhatis cron scripts get run close to each
other to keep
# them from stepping on each other's toes.  The worst
that will
# happen is that they will temporarily corrupt the
database...
[ -f $LOCKFILE ] && exit 0
trap "rm -f $LOCKFILE" EXIT
touch $LOCKFILE
/usr/sbin/check_mailscanner -q # >/dev/null 2>&1
exit 0

which runs MailScanner if it's not started. These
scripts are good when you're running on a single host,
but in a cluster they only cause problems for the
standby node.

I guess all I have to do is remove the cron job and be
sure to set a monitor on the process to tell me when
MailScanner is shutdown.

Thanks for the advice Peter.

Michael.
