Not something I can run, but http://www.mailradar.com/ seems like a better free service. They let you monitor 5 IPs for inclusion on blacklists which works better for a personal setup where you might have more than 1 domain but wouldn't have more than a couple VMs as the MX servers.

I signed up for mailradar.com and the confirmation email landed in the Spam folder of my Gmail account.
