It certainly isn't for everyone, nor
does it intelligently discern.

The point about including the US zone is very valid as you noted, it 
ranks amongst the top countries of
spam origin. The networks I service however receive a significant amount 
of email from the US and although
a percentage of it is Spam, the majority of it is legitimate. Most of 
the other countries in the zone however send

I have been using this for a quite a while and when going back through 
the list posts I noticed there were some individuals
who were interested in blocking by country.  I only posted it because of 
this and to save folks who wanted to do it the need
to include individual zones provided by
