Great advice John! You should also forward the email to
spoof@paypal.com -if it is one that supposedly came from paypal. If it is a phishing email from ebay then forward to
spoof@ebay.com . They will then check into it...trying to catch these people. Plus they will also verify for you whether it is real or phish.
They also advise that to find out if it is real or not to sign into ebay and check your messages there. They always send one to your messages and to your email.
