Just seen this on Action Fraud's website - a warning to watch out for emails pretending to come from PayPal, telling you that you have recently changed your email address. The idea is to make you respond to them to tell them that your email address has not changed and you don't want your account to be frozen. Responding to them actually means you are responding to fraudsters, who could use your information to commit fraud using your name.
Something to be careful about, especially at this time of year!
