Helm Chart not properly configuring SMTP_SECURE, SMTP_HOST, SMTP_USER, SMTP_PASS and SMTP_PORT

[Routhinator]

Describe your Issue

When using the mail settings in the helm chart, many of the resulting values bound to the pods environment variables are defaults and not the configured settings.

The only ones that work properly are MAIL_DOMAIN, MAIL_FROM_ADDRESS and SMTP_AUTHTYPE.

Logs and Errors

Errors: Email sending does not work. Validating the configuration by inspecting the pod yaml makes the problem clear.

From the nextcloud pod (fetched with get pod -o=yaml)

    - name: MAIL_FROM_ADDRESS
      value: nextcloud
    - name: MAIL_DOMAIN
      value: private.com
    - name: SMTP_SECURE
      value: ssl
    - name: SMTP_PORT
      value: "465"
    - name: SMTP_AUTHTYPE
