Replaces Postfix TLS files for SMTP and reloads after validation.

The service agent on the server fetches the task from the appliance over outbound HTTPS on port 443 and installs the certificate locally on the server. The appliance never connects to the server.

What happens

  1. The service agent on the server fetches the task from the appliance over outbound HTTPS, port 443.
  2. The TLS files named in main.cf are written and validated.
  3. Postfix is reloaded. If it fails: Rollback puts the previous files back and reloads.
  4. Verification: the package validates the configured TLS files.
