Anyone received an email from API DNR

Have recently received an email from API DNR (apidnr.com.hk) notifying me that they are representing a client who would like to register a domain name that uses “my domain name” as the key word?

Today I noticed in another email account for another domain name I own the same request for that domain name.

Is this a scam, the refered to web site today is off line – was ok yesterday!

What I would like to know is what can they gain from such a scam (if it is a scam)?

Cheers.
