About the only thing you can do is track through the "Received" headers of
the message to see which server(s) the message has passed through.  That
will at least give you an idea of which ISP it was sent from.  Some servers
wil also include the IP address of the original client that sent the
message.  But there is no single direct way to validate the email address of
the sender, without access to the server-side logs.

Yes.  Spammers fake that all the time.
