That’s not because you have a wildcard. That’s because you need to implement DKIM, DMARC, and SPF records to prevent others from using your domain name to send mail.

Well I used a third party service to host my domain, and as far as I can remember (like I said this was over a decade ago, maybe almost two decades), everything was set up correctly at that time.
Not trying to dispute what you said, but I can at least speak towards that as far as we knew at the time we had the domain set up correctly on our end, the stuff we could control.
The only thing is we had a catch-all bucket setting turned on for emails to be forwarded to an internal email address of our domain.
