Until recently I didn't get that mNY spam emails and those that I did get I was able to block or write a rule to send them straight to the trash. Recently I've started getting a lot of spam email where I am not only the recipient but I am also listed as the sender. If I hit reply it comes up with my name and email as the recipient and sender. I've looked at the 'raw source' and 'return path' to see if I can determine the actual sender but have had no luck.

Is this type of spam something new? Is there a way to find out who is actually sending this stuff?

Thanks in advance.
