I've heard of a few US government network operators who have attempted 
to block "chinanet" by refusing all traffic from 202/7, but I certainly 
haven't noticed widespread problems sending mail from addresses within 
202/8 and 203/8 (although I have done no systematic testing).

What is a "significant number"?

Is this really a widespread problem, or is it just an enduring myth?
