Testing my KumoMTA instance; I have successfully received messages from Gmail.
My next test step was to try and send to Gmail.
swaks --to <me>@gmail.com --from me@<my domain> --add-header 'message-id:<uuid>' --ehlo moto --server 127.0.0.1 --port 25
I see the following in kcli trace-smtp-server
[root@srv1081723 ~]# tailer --tail /var/log/kumomta

But it’s not landing, even as I’m monitoring All Mail if/when it lands in Spam.
