Raidco Kerala Limited — Email Infrastructure Rebuilt, Then Evolved
A 100-user email migration from fragmented platforms to a unified system — and three years later, an infrastructure upgrade that shows what a long-term technology partnership looks like
A fragmented, multi-domain email setup consolidated into a single secure system — then evolved three years later into a modern, maintainable infrastructure
100 users migrated. Multiple domains unified. Zero data loss. And when the infrastructure needed to evolve, Raidco called loreD again

The Starting Point
Raidco Kerala Limited had 100 email users operating across multiple domain names and multiple email platforms simultaneously — some on shared hosting, some on Google Workspace. The fragmentation was not intentional. It had accumulated over time as the organisation grew and different departments or subsidiaries adopted different solutions
The practical consequences were significant. Email from one domain could not be centrally managed alongside email from another. Security policies were inconsistent across platforms. IT administration was duplicated across systems instead of managed centrally. And with sensitive corporate communications distributed across platforms of varying security maturity, the data protection exposure was real
The brief was not simply to migrate email. It was to consolidate a fragmented communication infrastructure into a single, manageable, secure system — without disrupting 100 users in the process
Phase 1 — The Migration
ASSESSMENT
Understanding the Infrastructure Before Touching It
The first step was a comprehensive audit of what existed. Multiple domains, multiple platforms, varying configurations, years of accumulated email data across different systems. Before any migration planning began, we mapped the complete picture: which users were on which platforms, what data needed to move, what configurations existed, and where the dependencies were. A migration without this foundation produces surprises at the worst possible moment
SOLUTION
Zimbra + SpamTitan — One Platform, One Security Layer
We recommended and implemented Zimbra Collaboration Suite as the unified platform — an open-source enterprise email and collaboration system capable of hosting all of Raidco’s domains under a single administration interface. Every user, every domain, every inbox managed from one place. SpamTitan was deployed as the email security gateway — filtering inbound email before it reached user inboxes, significantly reducing phishing exposure and spam volume. Critically, both platforms were self-hosted on infrastructure Raidco controlled, not dependent on third-party SaaS pricing or policy changes.
MIGRATION
100 Users, Multiple Domains, Zero Data Loss
The migration was sequenced to minimise disruption: users migrated in groups, with the existing platforms kept live until each group was confirmed operational on Zimbra. All existing email, contacts, and configurations were transferred. DNS records were updated with timed cutovers to prevent mail delivery gaps. User training was delivered in parallel with the technical migration — so staff arrived at the new system with working knowledge, not just access. The entire migration was completed without a single reported email loss
Phase 1 Results
Raidco moved from fragmented, inconsistently secured email across multiple platforms to a single unified system — administered centrally, secured consistently, and fully under their own infrastructure control
Platforms
Multiple (shared hosting, Google Workspace, others)
Single — Zimbra, all domains unified
Administration
Separate login and management per platform
Single admin interface for all 100 users and all domains
Email security
Inconsistent — varied by platform
SpamTitan gateway applied uniformly across all inbound email
Data control
Partial — some data in third-party SaaS
Full — self-hosted infrastructure under Raidco’s control
User disruption
N/A — pre-migration
Zero reported email loss. Training delivered alongside migration
Phase 2 — The Evolution
Three years after the initial migration, Raidco’s email infrastructure needed to evolve. Zimbra, running on the original VPS configuration, was being succeeded by a more modern architecture. The organisation’s scale and operational expectations had evolved, and the infrastructure needed to match
loreD migrated the Zimbra installation to Mailcow — a modern, Docker-based email server with a cleaner administration interface, stronger default security configurations, and a more maintainable infrastructure architecture. The migration preserved all existing email data, maintained continuity of service throughout the transition, and delivered an email infrastructure better positioned for the next several years
Why Mailcow over Zimbra?
Mailcow is a modern Docker-based mail server that is significantly easier to maintain and update than a traditional Zimbra installation. Cleaner admin interface, more frequent security releases, better alignment with current infrastructure practices. For an organisation that has been running self-hosted email for several years, the migration to Mailcow is the natural evolution — preserving the data sovereignty and cost advantages of self-hosted email while reducing the administrative overhead.
SpamTitan remained in place as the security gateway. The security layer did not need to change — only the underlying email server.
loreD handled our email migration when our infrastructure was in a complicated state. They understood the multi-domain complexity, moved everyone across cleanly, and the system has been solid ever since. When we needed to upgrade the infrastructure, there was no question about who to call

What This Engagement Demonstrates
The Raidco engagement is the clearest demonstration in the loreD portfolio of what long-term infrastructure partnership looks like — not a one-off project, but an ongoing relationship where the technology is actively managed and evolved
Infrastructure assessed before it is touched — no assumptions made about what exists; every migration begins with a complete audit
Migration sequenced to protect operations — 100 users moved without a reported data loss or service gap
Open-source platforms that deliver enterprise capability without per-user licensing costs — Zimbra and then Mailcow both chosen specifically for data sovereignty and long-term cost efficiency
Security deployed as a system layer, not an afterthought — SpamTitan applied at gateway level across all inbound email from day one
Infrastructure that evolves — when Zimbra needed to be replaced with a more maintainable architecture, the same team that implemented the original migration handled the upgrade
Running Complex Email Infrastructure?
If your organisation is operating across multiple email platforms, struggling with inconsistent security policies, or running self-hosted email that needs to be migrated or modernised — the same principles apply: assess first, plan the sequence, migrate without data loss
