@Jerry@hear-me.social There’s also a null MX record for the sake of completeness https://serverfault.com/questions/714052/why-is-rfc-7505-null-mx-necessary

@momo Yep, people have mentioned it. I went back to try it and discovered my ISP does not allow a null MX record to be added. If it can be done, it's great, but an SPF that says nobody can send email should do the trick. If you could do, that's better.
