@ryanc probably yes, but fastmail and gmail delivered the mail. Would like to see some other resolvers and what happens too. Mostly tried linux based stuff myself. “host cname dot fyi” returns some interesting results! (Vis “dig MX cname.fyi”).
With just a mail dot cname dot fyi mx record postfix complains about a mail loop..

You should be able to email dnscrimes at cname.fyi as well as resolve foo.cname.fyi and there's also a lower priority MX record for mail.cname.fyi that is CNAMEed (also bad) #dnscrimes -
