### *Postfix in a Service* ###

A Postfix container with TLS support

#### **TLS**

You need to generate the certificates for postfix to use. At present i'm using kubernetes secrets to pass the certs into the container

```shell

  # Generating a self-signed certificate

  [jest@starfury docker-postfix]$ openssl req -new -x509 -days 3650 -nodes -out postfix-cert -keyout postfix-key

  # You have to base64 encode them and place them in kubernetes

  [jest@starfury docker-postfix]$ head postfix-certs.yml

  apiVersion: v1

  kind: Secret

  metadata:

    name: mail-certs

  data:

    postfix-cert: |
