You really do have to be very careful in replying to ANY eMails from PayPal. Nothing bad about PayPal you understand....but there are a lot of hackers trying to scam (not SPAM) PayPal users.
The best way to deal with those emails is to copy them, send them, delete them and then independently log into your PayPal account by going to their website. You should then report the eMail to their Security Group. If there is any action you need to take based on information provided through your secure log-in you will be made aware of it there and know it is authentic.
