Great!  Thank you.  I just have to check if the domain is in hosteddomains 
(grep -qx is easier than dig and compare its results).

I have it installed as readable and executable only by root, even though it's 
in /usr/local/bin.  Are there reasons for that?  I'd call it from an 
unprivileged script.


Best
