The last one is first. So this came from a web interface (HTTP) to some unknown sender. And this says basically nothing useful.

More often, the "last is first" Received indicates that a home system (i.e. res-something.comcast.net) originated it, meaning that someone's home computer was malware'd into sending spam or more malware. And messages like this usually have the home-ip address that can be traced (traceroute) and reported. Those rarely change (except possibly when someone reboots a home router), so they aren't definitive (except to certain swat teams that don't care to do their homework), but they can help get a home system off the internet until they are cleaned up.

Footnote: if you can save the full-headers (or message source) message as a text file, it's one command in vim to filter it
vim: v/^Received/d

Good luck.
