I agree. In fact, the only check is if it contains the @ symbol, since "com" and other TLDs/gTLDs can have MX records, it is possible to have email@com. Not that we'd ever see it in practice though.

@Zikeji It's possible for TLDs to have A records, and for a while there were a few that did. But ICANN forbids top level A records, and I wouldn't be surprised if they forbid top level MX records as well.

Anyway, you would literally enter the address as "email@com." including the trailing dot, which represents the DNS root that contains all the TLDs. You can also think of the trailing dot as an indicator of a FQDN (instead of a hostname within your local search domain).
