Mail queue notifier script for qmail
This is a shell script that I wrote that checks the Qmail mail queue size and if it is above a given number it will send an email alert. With this handy script you can be notified of when your mail queue is filling up before you run into problems. This can easily be added to a cron job. You may have to change some of the script to make work on your system.
