        // consider the authentication as succeeded as we did not get an error
        next();

    done();
};

how would you wire this into the default.js?

"modules/authplugin": {
enabled: true
}
?

Still don't working...???

Does not seem to work in 2020.

For a real production example see the authentication in zonemta-wildduck plugin.

In addition of enabling an authentication plugin you also need to make sure that authentication is even enabled for the smtp interface in ZoneMTA, otherwise the authentication plugin is never called.

autphlugin.js is a typo - it should be authplugin.js - Unfortunately, I can't seem to get the authentication working. @andris9
