7.4 SMTP/Email Notes

Orbnetes deployment and release orchestration documentation for operators and platform teams.

Email delivery is typically required for approvals and release notifications.

Minimum SMTP fields:

  • host,
  • port,
  • encryption (tls/ssl as required),
  • username/password (if auth enabled),
  • from email/name.

Operational guidance:

  • Use organization-managed SMTP relay when possible.
  • Ensure SPF/DKIM/DMARC alignment for sender domain.
  • Prefer dedicated sender mailbox for platform notifications.
  • Keep SMTP credentials in secure storage and rotate periodically.

Troubleshooting hints:

  • auth failure: verify user/password and auth mode.
  • timeout: check network egress/firewall to SMTP host.
  • no emails despite success in UI: verify project/user notification toggles and event eligibility.
  • provider rejects sender: validate from-domain policy.

Recommended test flow after changes:

  • send a test notification,
  • trigger a controlled approval-required release,
  • verify recipient set and email content links.
