Managed Cloud & Mail Infrastructure
Institutional and enterprise clients
Self-hosted mail, container deployment and DNS for organisations that need their data to stay where they can point at it.
A containerised mail platform with its own migrations, spool and retrying outbound queue, deployed to managed servers with SPF, DKIM and DMARC configured end to end. Built for institutions that cannot put correspondence on a third-party service — whether for cost, sovereignty or procurement reasons — and need someone to run it properly rather than hand over a box and leave.
Outcomes
- Containerised deployment with reproducible migrations
- Full SPF, DKIM and DMARC delivery configuration
- Monitoring, backups and documented runbooks at handover
Stack
- Docker
- Node.js
- Postfix
- Dovecot
- OpenDKIM
- Nginx
- VPS
Engagement
Client named under NDA. Several engagements are active public-sector contracts, so we describe the mechanism rather than the customer.
Source, references and a walkthrough can be arranged for serious evaluation.
The technical dossier for this engagement
This page describes the shape of the work. The dossier describes how it was actually built — and goes to a named person at a named institution rather than onto a public URL.
- System architecture, including the integration boundaries and why they were drawn there
- The data model for the records the system is accountable for
- Security posture: authentication, authorisation, audit trail and key handling
- Deployment topology, failover behaviour and what happens during an outage
- The measured before-and-after, where the client has cleared it for release
- Named CVs for the engineers who did the work
Sent under a mutual NDA. Client names and locations are redacted unless that client has given written consent, which some have and some have not. Prepared individually — expect it within two working days, not instantly.

A 30-minute technical briefing. We will tell you what we would build, roughly what it costs, and honestly whether we are the right people for it.
