I have received a suspicious email regarding my domain. Who can I contact?

The email reads: "Dear Mr. / Ms.,
We are a domain registrar. Today we received an application from Fiona Yu International. They apply for registration of cquestmarine Brand Name and several cquestmarine domain names associated with your company name. We are not sure about your company's relationship with this company.
Now, we are processing this application. We need to confirm whether this company is affiliated with your company. If so, we will continue the next step of registration. If not, please let me know as soon as possible in order that we can deal with this problem in time. Thanks for your time."
