How can I tell if an email has been sent directly, or redirected on the way?

How can I tell if an email has been sent directly, or redirected on the way?

I've been receiving email from a company, but they claim I'm not on any of their email lists and that it must be getting forwarded by one of their clients.

"Looking at the headers, you should be able to tell every mail server the message touched. For example:

Follow the Received lines. We can see the message bounced around some internal google servers (10.239.137.15 and 10.224.83.85), that google got the message from bmsmail5.ieeedotorg [140.98.193.25], but that the first smtp server to send the message was dct1-lb-191-papp1.ieeedotorg [140.98.191.254]"
