Steve, there was no doubt in my mind that it was a spoof email. For one thing, a real email sent via the eBay internal email system (which this was made to look like) would have my full name (Robert Eisenstadt ) at the very top of the email, and this one didn't. I assume that they wanted me to hit the "please respond" button to get sensitive secret matter (ebay password, who knows what else?). Why else would they send it? I automatically don't even think of hitting the respond button to see what they want, because it could be a virus perhaps. Maybe just responding would tip them off to my valid email address. I don't know, but why take chances?

P.S. I forwarded the email, as I always do (with the header pasted on), to "eBay (spoof@ebay.com)"
They have already replied that it was a spoof email.

Robert
