If the email includes your eBay ID, is in reference to an actual auction you have listed, and the links all actually point to eBay, it's probably legit. Here is a snapshot of a scam I got this morning. It says "your registered EMAIL is included to show..." My EMAIL is included because he sent it to my EMAIL address. Who knows where he got my email address. Everybody has by email address! That's how I get spam!!! The email does NOT include my eBay ID. The auction is nothing I have ever had anything to do with. And most of the links are to a numerical address, not eBay. This scam is particularly stupid, since it says "seller has responded" but the message is something a buyer would say. I've seen better !
