The true answer is no. The reason is that different people write their valuators based 
on different criteria. For example:
\.[a-z]{2,4}$ - means that the string has to end with a period followed by a 
combination of characters that must have a length of 2-4. This gets .uk and .info with 
no problem as they're official domains. On the other hand, someone said that .museum 
is now a legal domain and that means that the code has to be {2,6} now. 
I'd say take a few of the best ones, look at them to decide why they were done 
differently and then roll your own. 
Oh, a side question. Do you want to do pre-sending validation or post?
