I use the following to do just that. I'm sure there is a better way but I
fudged this together myself
Script 1:
#!/bin/bash
/usr/bin/mailq | /usr/bin/tail -n1 | /usr/bin/gawk '{print $5}' >
/etc/postfix/mailq_count
Script 2:
#!/bin/bash
mailq_count="/bin/cat /etc/postfix/mailq_count"
if [ `$mailq_count` -gt 50 ]; then echo "Mail count on Server is"
`$mailq_count`|/usr/sbin/sendmail -f r...@example.com repo...@example.com ; fi
These run as cron jobs every few minutes.
Hope that helps.
