Dear Google AdWords Customer,

Please sign in to your account at http://adwords.google.com/select/login , and update your billing information.
Your account will be reactivated as soon as you update your payment information.
Your ads will show immediately if you decide to pay for clicks via credit
or debit card. If you decide to pay by direct debit, we may need to receive
your signed debit authorization before your ads start running,
depending on your location.
If you choose bank transfer, your ads will show as soon as we receive your
first payment.


We look forward to providing you with the most effective advertising available.

Sincerely,

                                                                                                                                                                  • -

しかしHTMLメールを見ると、URLが
http://adwords.google.com.suh12.cn/select/Login/
だったりして、明らかに詐欺メールであることがわかる。
また、HeaderをみるとReply-To:が @yahoo.comだったり経路が明らかにGoogleからではないこともわかる。
