Hosts do not identify themselve as domains! Hosts can use domain as part

Hate to be pedantic, but even back in 82[12] days the email RFCs
identified email addresses as (meaning, not the literal BNF):
<local-part>@<domain>
Thus, the HELO domain can be indistinguishable from a fully
qualified domain name. But it _is_ the domain for email purposes.
