No. it isn't. DNBDNS has always been immune to this kind of stupid coding.

I am of the opinion that there are no impenetrable systems in this world.
True. But some are better than others.
Dan Berenstein has had an offer open for 10 years of a $500 reward for anyone that could show a flaw in his QMail software.
That offer remains unclaimed.
He has an identical offer open for DJBDNS.
$500. that ought to bring out the best! just kidding. I’ve heard about the qmail thing before.
