I received an email this morning that I was confused / concerned by. I am looking at the headers however I am not sure exactly how to make this out. This is obviously spam and I did not send myself spam. The sender shows my email address as well as the recipient address however when I view the full message headers, I can see the 'Return Path' is to a different address. Does that mean that the headers were spoofed to look like I was the sender? Just trying to understand how to read this and also make sure I don't have a serious problem here.
