iredmail-kubernetes

Running the mail server with UI on minimal resources

You will need to forward the ports via ingress to the iredmail-server service. To do this, you need to force ingress to listen to traffic on these ports.

# patch nginx
kubectl patch svc ingress-nginx-controller -n ingress-nginx --type "json" -p '[
  {"op":"add","path":"/spec/ports/-","value":{"name": "smtp", "port": 25, "targetPort": 25}},
  {"op":"add","path":"/spec/ports/-","value":{"name": "smtp-ssl", "port": 465, "targetPort": 465}},
