My configuration looks like this:

target.remote outbound_delivery {
    limits {
        # Up to 20 msgs/sec across max. 10 SMTP connections
        # for each recipient domain.
        destination rate 20 1s
        destination concurrency 10
    }
    mx_auth {
        dane
        mtasts {
            cache fs
            fs_dir mtasts_cache/
        }
        local_policy {
            min_tls_level none
            min_mx_level none
        }
    }
}

Maddy version 0.7.0
Is this the expected behavior?
