Is anyone else experiencing this..... 

I have items for sale currently and I have been receiving emails from "potential customers" asking me questions about postage of items etc.  The questions come to an email account of mine that is not connected to my ebay account and the sender's email address is eBay <noreply@ebai.com>.   Everything about the email looks identical to questions I receive from geniune ebayers.  I haven't responded (and won't) as alarm bells rang when the emails came to a different email account and the questions were abit strange (eg. asking how much postage would cost to Perth when all my items are sent in pre-paid satchels).   I am not sure what happens if you hit the Respond button and I am not going to find out!! 

Does ebay follow these sorts of things up like the banks and the ATO?
