If the troubleshooting steps do not help you resolve your issue, please make sure to provide the following when asking for help:

  1. The version number of your KumoMTA instance, found using /opt/kumomta/sbin/kumod --version

  3. The full text of the init.lua policy script running on the KumoMTA instance.

  5. An example of the Swaks call that reproduces the issue. See the Swaks documentation for instructions on how to use Swaks. This allows us to reproduce the issue and removes external factors from the issue at hand.
