ah! I see clearly now. You've answered my confusion.
I have all 200+ entries (one for each country) to see how things are flowing and to build a model of which countries are contributing to my spam dealing headache.
(just for conversation sake)
However, if I would use the "zz" hostname would I also require adding a ton of country specific Lookup Values?
I'm sure using "zz" is more efficient.
I think you've set my confusion straight. I appreciate the reply!
Thanks!
