  • Decoding “Full Headers” in Apple Mail, so that I may block a spoofed-domain

    Posted by Randall Blanchard on August 5, 2021 at 5:29 pm

    Some political organization, supposedly originating in Arizona, KEEPS spamming me, from a “spoofed” e-mail domain, and I would like to be able to block them using my ISP’s “block list” of domains .

    Now, I’m on a 2015 MacBook Pro, running macOS Catalina v10.5.7+Security Update 2021-004, and using its Apple Mail, so I can “View” one of the suspect e-mail’s “Message”s, with “Full Headers”, but I don’t know how to decode the “full header”, so that I can discern the ACTUAL e-mail’s source-domain .

    Can you help ? — I DON’T want to get trapped, into clicking upon one of the e-mail’s “Unsubscribe”-links .
