Thanks for the response Mercenary. I hope I can contribute to the well-being of others through participating like this. Regarding the full header, since I traced it back to the dubious site industrybusinesswebhosting.com through the "Click here to send resume" link, would the full header show additional useful ties?
This info was at the bottom of the email:
HostingBusinessWebsites 1220-100 L Street #462 NW Washington, DC 20005
Further checking reveals that is a box at the Mailboxes Etc. located there.
I can't find the option to show full headers on my mail service at this time.
I'll keep looking.
Thanks again for your response & good work at 419.
