kumo.listener_domain_field_names
Since: Dev Builds Only
The functionality described in this section requires a dev build of KumoMTA. You can obtain a dev build by following the instructions in the Installation section.
Returns the names of the options accepted by kumo.make_listener_domain, as an array of strings.
The list is read directly from the listener domain type in kumod, so these
are exactly the option names that kumo.make_listener_domain accepts.
Use this to classify a configuration key as a listener domain option before
deciding how to handle it, without calling kumo.make_listener_domain and
inspecting the result. The policy-extras.listener_domains helper uses it
this way to tell a listener domain option apart from other keys while
validating listener_domains.toml.
