Pre-built repos are available for supported Operating Systems, making installation straightforward:
This installs the KumoMTA daemon to /opt/kumomta/sbin/kumod
Alternatively you can install the kumomta-dev package in order to take advantage of the latest pre-release features. This is only recommended for testing environments.
KumoMTA is now installed with a basic policy that allows relay from localhost, but it will need a more granular configuration policy for production use.
Proceed to the Configuring KumoMTA section for more details.
