I register a **gmail.cn email account and try to mail to my several **gmail.com accounts. And find out that Gmail.com blocks emails from Gmail.cn...:)

Google does the right thing.

Google.cn has no affiliation with Google and will end up in court.

That's interesting. Maybe it was the right think to do, I believe so. But that's kind of precedence. Google has a great power and can make competitor's services useless. Without court's decision.
I think that this information should go to the first page (Philipp...).
