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/sslas 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.
