You will hear it mentioned frequently in genuine emails from eBay or Paypal, that they "will never ask you for your user name or password in an email". In fact, eBay UK's most recent statement near the end of their emails is "eBay will not ask you for sensitive personal information (such as your password, credit card, bank account numbers, National Insurance numbers, etc.) in an email."
So if you recieve an e-mail from ebay or paypal asking for personal details do not fill anything in, If you believe the e-mail in genuine then go to the eBay home page and log in go to your message center and if theres been an important e-mails sent to you there be a message at the top of the message center talking about it this is called an 'Alert'.
QUESTION, I've got an email from eBay this must be real as its from ebay.com?
ANSWER, the ease in which almost anyone can forge an email and almost all its header information due to a security loophole in the set up of SMPT mail servers (POP3). It is a certain fact with any email that the sender, as shown in your mail program's inbox, is absolutely no guarantee of its true origin.
