Spoiler alert, it’s Postfix. So not really 1984 software. But then again, neither is Linux…

Almost everything described in the article didn't exist in 1984. Postfix, OpenDKIM, TLS, SPF, DKIM, DMARC. Only very basic SMTP and DNS, but even MX records didn't exist.

OpenDKIM seems dead:

But the experience of using mailx is close to that time, hence the title. Even though I’m too young to know for sure :)
