What version of MailScanner are you using? This was a known problem with
some of the early releases of version 3. You really need to be running 3.04.

Running /usr/local/MailScanner/bin/check_mailscanner should restart
MailScanner if it is not running.

How about something like

#!/bin/sh

# Define this to be your maximum allowed mail queue length
MAXLEN=300

LSLEN=`cd /var/spool/mqueue.in && ls | wc -l`
QUEUELEN=`expr $LSLEN / 2`
if [ $QUEUELEN -gt $MAXLEN ]; then
   /sbin/reboot
fi
