You add either their IP address, or the hostname to which it resolves,
to /etc/mail/relay-domains.

With relay_entire_domain, you can add partial IP addresses or domain
names to the relay-domains file.

You should be able to add RELAY entries to the access_db, and ignore
the relay-domains file.

access_db is an optional feature, and the RELAY tag is new in 8.9.1.
Also, it only applies to the sender. The relay-domains file allows you
to specify that relaying *to* a particular domain is permitted (which
is necessary if your host is acting as a backup MX for one or more
domains).
