I was aware that messages like these, designed to basically bluff their way into extorting victims, had been appearing for well over a year on the Internet. All seemed to follow a similar format. And have been pretty much discounted as fake. In my case, the threat was laughable. I simply don't do those sorts of things.

I was also aware that anti-SPAM software can sometimes mislabel legitimate messages. Therefore, whether or not Google flagged it as SPAM (which in this case it did). this definitely needed to be investigated.

The first thing I checked, of course, was my "sent" email folder. The received message was not there. I was happy to see this, but it still didn't prove the account had not been hacked.

The good news is that there is an easy way of finding out how that email really got into your inbox. To do this, simply click on "Show Original" using Gmail, or the equivalent option when using other email systems.

This lets you see the underlying header codes, which show where messages came from, and how they have been routed through the Internet on its way to your inbox.

The headers, which start with the word "Received: from " should be read chronologically from bottom to top — the oldest, which is where the email actually originated from, is at the bottom.

So, I looked at the bottom of the mass of headers that were there, and found that my message had actually originated from a computer located in Texas.

The email was sent through a rogue SMTP server that has been known for sending spam. My guess is that the message itself likely originated from a botnet running on an infected computer in Plano Texas. We are following up on this. What is more important for me to know at this time is that the email headers proved the message I received did not come from our systems.
