So far fairly typical.

The "myorigin" parameter is used to add @domain qualifiers to
bare sender names, and so should be a domain you accept email
for (as opposed to a host other hosts connects to). So typically,
these days, most sites have "myorigin = $mydomain" set to the
primary email domain for which the MTA accepts mail.

The myhostname parameter should be fully-qualified domain name
that matches the PTR record of the machine's primary external
IP address. Otherwise, at least one of the MX hostnames of
the primary email domain.

Same as myorigin, a public valid email domainname.
