eBay Scam: Unpaid Item Reminder border="0" height="318" width="500"/>

Never trust the links from such mail. What you "See" appears to be from eBay. But if you mouseover the link, it actually sends you to the following:
ftp://Administrator:herb@65.83.13.163/ne.html

Its a FTP address containing the UserID: Administrator, and the password "herb", which will automatically logs you into their server. After that, their webpage will be loaded up via your browser, and you will the this ne.html (eBay lookalike), which likely contains phishing scripts.

Whatever information you entered here will be captured by the scammers.
