I Have Received An Email From Paypal Concerning My Account Details.

To verify the E-mail you only need to check the return path. Select the e-mail and in Outlook Express look for properties. Open the properties of the e-mail and select details. You will see a line at the top stating the return path. If this does not refer to Paypal then I suggest you delete it. In any case if I have any suspects on E-mails I will delete it or put it into a folder for scam mails. If you hear no more, then you can delete it. Do not open the mail until you're certain it is valid.

'If in doubt chuck it out'

The simple answer is no. That is a phishing email, just delete it. PayPal will never ask for your account information in an email.
