note 9613 added to checkdnsrr

The above code appears to run flawlessly, although when put to the test there appears to be a hole in it. Every time a domain known not to exist is typed in without a proper ending (i.e. leaving off any sort of ending such as .com) is entered after the @ symbol getmxrr() fails, but checkdnsrr() returns "TRUE". In my testing I found that by converting the domain to an IP Address first, and then running it through checkdnsrr() it appears to function correctly. I realize that this is probably unnecessary due to the fact that such a domain wouldn't pass the initial rational expression in the above example. But maybe this will help some of you who are using checkdnsrr() in some other way. :-) By the way, everytime I pass getmxrr() a domain ending in .tv it returns "TRUE" and the IP Address 64.209.167.41, although the name is not registered in the WhoIS database or on www.tv! Is there any way to check whether or not the .tv domain really exists or do all of the .tv endings have the same IP Address somehow? http://www.php.net/manual/function.checkdnsrr.php
