EdBobs..here's a handy hint.
I have my email to show headers..and when you pull the email up it'll tell who the ISP/carrier that emailed you.
ALSO always, always check your My Messages with eBay..if it's from eBay it will be there also.
Hover your mouse over links if you want to be sure..but never click. If the hovered mouse doesn't designate eBay or Paypal...then scoot it over to spoof@ebay.
