If you think you’ve received a suspicious email or have been directed to a fake website, forward it to email@example.com and we’ll investigate it for you. After you send us the email, delete it from your inbox. If you clicked on any links or downloaded any attachments within the suspicious email or website, log into your account and view your transactions. It’s also a good idea to change your password.
I just got the following e-mail from "PayPal". How can I tell if it is really from you?
You can login to your PayPal account and check disputes on your right.
If you really have a dispute then there will be notification in your paypal account as well.
Hopefully it helps.
