TLDs are limited and prevent FPs of that particular nature.

Sure, but there are lots of ccTLDs that could be confused with English words, never mind other languages.

Do you really want SpamAssassin to do URIBL lookups for invented.by (Belarus) for a sentence like "The www, invented by Tim Berners-Lee, ...", or billy.jo (Jordan) for "On the www, Billy-Jo can be heard..."?
The processing overhead would be enormous.

I'd suggest performing your own dns lookups against the domain first to make sure it's valid, before doing the uribl lookup. Eg:

m...@haven:~$ host -t ns invented.by
invented.by does not exist, try again
m...@haven:~$

You'd also want to cache your results. This conversation however is pointless. Why not just try it and see how well it works.
