This is an interesting one, I think. This email tells you that this 'wrong' email address that YOU just defined was accepted and will be used in 3 days as the official one. Of course, if you have a PayPal account you probably want to rectify and give away your password... That's the trick here. Notice that the link goes through Google which obviously would not accept PayPal just like that, especially without mentioning it.

Also, this one includes the address of paypal so they worked a little bit at it. Of course, it starts with a straight IP address, and as usual, the guy did not even create an SSL server (which he cannot without getting that message "warning, you are entering an encrypted site without 3rd party signing for it." You need credential verification for that purpose and thus people don't usually do it.

You have added undergroundseller@yahoo.com as a new email address for
your PayPal account.

If you did not authorize this change , or feel there is an error made ,

If this change was initiated by you ,
the new email address will be set as primary within 3 working days .

Thank you for using PayPal!
The PayPal Team .
