RFC 821 defines the syntax for mail domains, not domain names in general.

Host names are not mail domains. RFC 952 defined the syntax for host
names. RFC 1034 recommends that labels in the DNS follow either 822 or 952
syntax (which are mostly the same).

All of these were updated by RFC 1123 to allow leading digits.

Internationalized domain names do not affect the restrictions on the
syntax of what is put in the DNS.
