I mean a luxury as in if you are so fortunate to only receive mail from a few regions or so. We have a fairly large customer who is an electronics manufacturer, their suppliers and customers are all over the globe, unfortunately we can't use this strategy for them.
We have a few financial customers, however, where their customers are only in the US. They block access to all of their resources geographically, this seems to work very well for them for spam and attacks.
Very nice work Mark. How do your logs look with all of those log statements?
