LinuxQuestions.org - genuine or phishing for email address

I'm the (acting) webmaster for the Roodepoort Hiking Club (RHC). I received the following email and I'm trying to figure out if this is a genuine request or some kind of phishing. I went to whois to check the domains, but still can't figure it out.

Dear President&CEO,
We are a professional intellectual property right consultant organization in Asia, who mainly deal with the global domain name registration and internet intellectual property right protection.
Right now we have an important issue to confirm with you. On October .9. 2009, we formally received an application, one company named " Jacken S&T Info Corp." applied for the brand keyword " Rhc" and following domain names:
rhc.cc
rhc.com.hk
rhc.hk
rhc.tw

with our organization
During our preliminary investigation, we found that these domain names' keyword is identical with your trademark. I wonder whether you consigned Jacken company to register these domain names with us? Or is Jacken company your business partner or distributor in Asia? If you have no relationship with this company, we assume that they have other purposes to obtain these domain names.
Currently, we have already postponed this company's application temporarily. Therefore please let the relevant person make a confirmation with me by telephone or email as soon as possible.

Thanks & Regards,

Loudyn

What I don't trust are the 'mismatches' between email addresses (address1@rhc.org.za and address2@rhc.org.za for the recipient and ...@gmail.com, ...@chinaonenet.org etc for the 'sender'.

Any help appreciated.
