Someone already reported this issue (which is unfortunately not available anymore as it was on the previous bug tracker), and a non-documented fix already exists: just add backend.extensions.id.send-after-auth = true to your config file. See modern-email/defects#25 for more context about this defect.

Let's keep this issue open for documenting this option.
