OK, thanks, I get this. However, this IS (should be) allowed?:

www.urad.si	CNAME 	urad.blogspot.com


Like I said in my original post, I have already read this http://www.nabble.com/CNAME-answer-problem--t4246749.html but still

dig @dns1.arctur.si www.urad.si

returns NXDOMAIN


dig @dns1.arctur.si +norecur www.urad.si

resolves domain as it should ...

And like I already said, my PDNS Recursor @dns1.arctur.si works just fine, If I dig an external domain directly, everything is OK:

dig @dns1.arctur.si urad.blogspot.com

What could I be doing wrong?

Kind regards, Marko Kobal.
