It actually works very well with very small and very large distances.
I suppose it COULD.
Anything that I receive from an IP address located with maybe 50
miles of my
location is almost 100% guaranteed Ham. However, I've never received
even a
single email from China that wasn't spam.
That has nothing to do with distance though; that has to do with it
being China and you not speaking Chinese or having friends in China.
I get ham from Australia, New Zealand, Thailand, Japan, German,
France, the UK, Spain, Mexico, Venezuala, Guatamala, Sudan, and South
Africa. I do not receive ham from China, Korea, Taiwan, or Brazil.
Distance is not a good measure.
This probably has more to do with the absolute location of people I
communicate with than the country or distance.
Yep.
What would seem to be really useful is if spamassassin kept the
geographic
coordinates for all sender IPs and created "hammy" and "spammy" area
mappings,
and used distance from these as a weighting factor.
That would be a lot of data to keep track of.
