[AccessD] It just goes to show ya

I frequently use MXToolbox.com to check how the world sees our DNS records (also to see if 
a client's IP addess is on any blacklists, to check whether their SMTP server is working and 
not an open relay , check that they have a valid PTR record etc).

To query different DNS servers, I use DIG - you can get a Windows CLI version here:
