Mail Notifications

Hephaestus notifies users when automated best-practice detection finds issues. Different SMTP providers are used in development and production.

Development setup (Gmail example)​

  1. Create or use a dedicated Gmail account.

  2. Generate an app-specific password (Google docs).

  3. Add the following properties to your application-local.yml:

    mail:
      host: smtp.gmail.com
      port: 587
      username: hephaestus@example.com
      password: <app-password>

    Alternatively, set POSTFIX_USERNAME and POSTFIX_PASSWORD environment variables.

Production setup​

  • Production uses a Postfix relay provided by TUM.
  • Copy main.cf and master.cf from ls1admin/postfix-container-tum-mailrelay.
  • Secrets and credentials are managed by the deployment team; avoid committing them to the repository.
