Looks like it turned out to be a ploy. At least I learned a negotiating lesson though (Dien).

I posted the same question on another board and received some responses. This response describes the contents of my email name for name:

Dennis...

This is a slick ploy by a spam harvester to build a list with verifiable email addresses... it's their way of checking which email addresses are live and has someone checking it and then adding the results to a database they can spam to...

I've gotten the same email asking about selling 20 of my domains... each one comes from the same person, uses the same email addy and tells the same story... in my case they were sent to me and signed by a "Mike Williams" with a return addy at MakeMeCeo.com... MakeMeCeo is owned by Cool Amazon and Jon Liu out of Stafford, TX and is hosted on Liu's servers (popularlink.com)...

Don't expect a response... do expect more spam mail... one other thing you might want to do is to keep an eye on your domain in the case it's just a precursor to hijacking your domain name... hopefully this is nothing more benign (if you can call it that) than being put on more spam lists (which, considering the amount of spam we all receive daily is not going to make a huge difference)...

Hope this helps...
