Just received this message. They seem to claim someone wants to register rainham-history in China. It's a complete scam. Why would anyone want or care to register something like that in Asia?
No-one manually checks domain registrations, they go through automatically so the whole premise of the emails is completely fake.
Dear CEO/Principal,This is Nicholas Lee---Senior Consultant of domain name registration and solution center in China. Here I have something to confirm with you. We formally received an application on May 15,2014. that a company claimed "RANGLANCE LTD" were applying to register "rainham-history" as their Network Brand and some "rainham-history" Asian countries top-level domain names(in/hk/tw/etc) and China (CN) domain names through our firm.Now we are handling this registration, and after our initial checking, we found the name were similar to your company's, so we need to check with you whether your company has authorized that company to register these names. If you authorized this, we would finish the registration at once. If you did not authorize, please let us know within 7 workdays, so that we could handle this issue better. After the deadline we will unconditionally finish the registration for "RANGLANCE LTD". Looking forward to your prompt reply.(This is a very important case, so please transfer this email to your CEO or Principal. Thanks a lot.)Best Regards,Nicholas LeeSenior Consultant Manager
