That means that the domain in question probably exists, but its 
nameservers are unavailable at the moment.

You don't want to do that; otherwise, you end up bouncing mail for 
aol.com in case aol.com's nameservers are unavailable (like if your 
own link goes down).

If the user misspelled the domain name to some non-existent one, 
you'd get permanent error from DNS, and bounce immediately.
