[OT] Help Reading Email Headers

Is there someone out there who can help me read the headers on some email I
have been getting?

I've been getting a buch of bounce messages comming back to me when I haven't
sent anything. It looks like someone has a virus and their computer is being
taken over to send spam and the virus and they are spoofing a
random name @star-ranger.com as the from address. (I doublechecked my
computer and no viruses)

I'd like to know if there is a way to find out who is sending out all those
bogus emails or if more than one computer is involved.

Send me an email directly if you can help.

Thanks,
