Hostkarma White list Updated and Improved

[Marc Perkel]

In the last week I've put a lot of effort into improving the accuracy of 
my white lists. Especially for those of you who are critical of the 
accuracy of hostkarma white list I'd like you all to test it now and 
tell me how it works now. I have to admit that I have been less 
motivated in the past about getting the white list right than the black 
list because people complain a lot more about good email getting blocked 
than bad email getting through.

Also looking for suggestions about how to make my white list bigger and 
better.

One thing that is different about my white lists is that it is supposed 
to be only sites that send good email. Most other white lists are just 
for keeping IPs off of black lists. Our white list is supposed to be a 
source of pure good email. So if spam comes for any of the white listed 
IPs then it's an error. Sites like yahoo, gmail, hotmail, etc. would be 
on our yellow list because they send mixed spam/ham email.
