Most of the spam I get comes from North America. Go figure. I'm not
about to cut access to that continent off.

I'd have to consider all other options really exhausted about fixing
this for myself before I have to go and fix it in the network in a way
that impacts other customers who may be getting spam from non-North
American sources, or who enjoy the North American spam...
