+# Development Mail Server
+
+You can deploy a fake smtp server which captures all send mails and displays
+them in a web interface. The [sample configuration](../templates/configmap.template.yml)
+is assuming such a dummy server in the `SMTP_HOST` configuration and points to
+a cluster-internal SMTP server.
+
+To deploy the SMTP server just uncomment the relevant code in the
+[ingress server configuration](../../https/templates/ingress.template.yaml) and
+run the following:
+
+```bash
+# in folder deployment/human-connection
+kubectl apply -f mailserver/
+```
+
+You might need to refresh the TLS secret to enable HTTPS on the publicly
+available web interface.
