This is great. I didn’t realize I had a couple of things wrong with my DNS configuration – particularly regarding safe and trusted email configuration on my home email server.
My friend and coworker Keith “King Cobra” Combs blogged about this site: www.DNSreport.com, which very quickly runs through a gazillion tests** and returns the results, with suggestions on how you can fix any errors or warnings that it finds.
I’ve since fixed the minor problems that it found.
