+GOOD NEWS!
+====================
+
+You've successfully installed the docker-mailserver helm chart!
+
+Initial Setup
+------------
+
+If you have not yet configured your mail server you'll need to quickly open a command
+prompt inside the running container (you have two minutes) and setup a first email account.
+
+    kubectl exec -it --namespace {{ .Release.Namespace }} deploy/{{ template "dockermailserver.fullname" . }} -- bash
+
+    setup email add user@example.com password
+
+This will create a file:
+
+    cat /tmp/docker-mailserver/postfix-accounts.cf
+
+Next, run the setup command to see additional options:
+
+    setup
+
+For more information please refer to this Chart's README file.
+
+{{ if .Values.proxyProtocol.enabled -}}
+
+Proxy Ports
+------------
+You have enabled PROXY protocol support, likely because you are running on a bare metal Kubernetes cluster. This means additional ports have been created that are configured for the PROXY protocol. These ports are in the 10,000 range - thus IMAPs is 10993 (10000 + 993), SUBMISSION is 10587 (10000 + 587), etc.
+
+It is now up to you to configure incoming traffic to use these ports. For more information please refer to this Chart's README file.
