We had a need to monitor the number of emails in the qMail mail queue. I wrote the following shell script to email you when your mail queue meets a threshold.
The best way to determine what to set the threshold at is to check the number of emails in the queue every few hours over a 2-3 day period. Allow for a spike of upto 100-200 emails then there is your magic number. You can check the number of emails in your queue by running /var/qmail/bin/qmail-qstat
We set our threshold at 1000.
All you need to do is set the Quota variable to your desired warning threshold, and change the email address in the mail string.
Throw this in the Cron and run it as often as you feel necessary. We run it every 10 minutes.
Don't hesitate to drop me a PM if you need help
Edit. I should note I have tested this on Plesk 7.5 and Plesk 8 for Linux. I will release a Windows version when I get time to do it.
Cheers

Code:
cd /var/qmail
messfiles=`find queue/mess/* -print | wc -w`
MIQ="$messfiles"
QUOTA="1000"
HOST="`hostname`"
if [ $MIQ -lt $QUOTA ]
then
echo ""
else
echo "Warning - $MIQ mails in queue on $HOST" | mail -s "EXPLOIT WARNING - Mail Queue" [email][email protected][/email]
fiAll you need to do is set the Quota variable to your desired warning threshold, and change the email address in the mail string.
