Describe the bug

The ingress template has changed since version 1.5.0 to use https instead of http. This results in Traefik responding with error 500 because the certificate of mailu-front is not valid for the host mailu-front.[namespace].svc.[cluster_domain].

Environment

• Kubernetes Platform: kubeadm cluster

Additional context

There are two possible solutions for this:

1. Revert the ingress back to using http instead of https
2. Add a Traefik ServersTransport for mailu-front with insecureSkipVerify: true, and reference it in the ingress template to bypass TLS verification for that host.

Option two will require some way of conditionally applying if Traefik is in use, of course.

EDIT to add: Option 3: make the http/https behavior an option in values.yaml (defaulting to https), this would be an easy solution.
