- Listmonk: newsletter/mailing list manager with PostgreSQL backend,
NodePort 32375, Postmark SMTP. Replaces Ghost's broken Mailgun-only
newsletter sending via n8n automation pipeline.
- Mattermost: team messaging manifest, NodePort 32374, PostgreSQL backend.
- Ghost: added Postmark SMTP config for transactional email, disabled
staffDeviceVerification on all three instances (Ghost has no TOTP,
only email-based verification which requires working SMTP).
