Hosted Business Email for IT Companies, Consultants & Resellers
IT KORR hosts business email on SmarterMail — and some of the organizations that buy mailboxes from us are themselves IT companies, consultants, and resellers provisioning email for their own downstream clients. Migration, domain and authentication setup, and ongoing support are handled directly, not through a subcontracted platform.

Where This Fits
One Coordinated Operating Standard
Reseller Email Hosting doesn't operate in isolation — it depends on, and supports, every other layer of your environment.
Interactive diagram of the 12 operational domains IT KORR governs as one coordinated platform: Microsoft 365, Identity, Networking, Firewalls, Servers, Storage, Backup, Cloud, Compliance, Business Continuity, Infrastructure Monitoring, Operational Governance. Each domain links to its service page — use Tab and Enter to navigate.

Part of the IT KORR Operational Platform
Every capability IT KORR runs — identity, networking, servers, backup, cloud, compliance, continuity, monitoring, and governance — operates as one coordinated system with shared dependencies, not a menu of standalone services. What happens on this page is sequenced against what comes immediately before and after it operationally.

Where Organizations Struggle
Common Reseller Email Hosting Challenges
Building mail infrastructure is not the business you are in
An IT company, consultancy, or reseller whose actual business is service delivery rarely wants to also operate mail servers, spam filtering, and deliverability reputation for every client domain it takes on.
Hyperscaler reseller margins are thin and inflexible
Reselling Google Workspace or Microsoft 365 mailboxes puts a company inside someone else's pricing, support model, and platform roadmap, with little room to differentiate or adjust for a specific client's needs.
Client domains need authentication configured correctly, per domain
SPF, DKIM, and DMARC have to be set up correctly for every domain added, or deliverability degrades silently — a burden that scales with client count if handled ad hoc.
Migrating a client off a legacy or consumer email setup
Moving a client from a personal Gmail-based setup, an end-of-life on-premises mail server, or a previous reseller relationship requires a migration path that does not disrupt their mail flow.
Support burden scales with every mailbox added
Password resets, mailbox provisioning, and spam-filter tuning for a growing base of client mailboxes becomes a recurring support load with no natural ceiling.
Hyperscaler support means a ticket queue, not a relationship
A client mailbox issue routed through a giant provider's support tier competes with millions of other tickets. Reselling through IT KORR means a direct support relationship instead.
Methodology
How IT KORR Operates
Domain & Migration Assessment
Current mail setup, domain count, and migration source (legacy server, consumer email, prior provider) reviewed to scope the move.
Mailbox Provisioning
Mailboxes provisioned on SmarterMail per domain, with DNS records and mail routing configured.
Authentication Setup
SPF, DKIM, and DMARC configured and validated per domain, so deliverability is correct from go-live rather than discovered as a problem later.
Ongoing Support
Mailbox administration, spam-filter tuning, and support requests handled on an ongoing basis as client mailbox count grows.

Technical Detail
Under the Hood
SmarterMail platform
Webmail, mobile device sync (ActiveSync), and administrative mailbox management are provided on SmarterMail — a dedicated business email platform, not a repackaged consumer inbox.
Email authentication
SPF, DKIM, and DMARC are configured per domain at setup, the same authentication architecture covered in IT KORR's DNS and email authentication guidance — deliverability is treated as a configuration discipline, not an afterthought.
Migration path
Existing mailboxes and mail history are migrated from the prior platform (legacy on-premises server, consumer email, or a previous hosting relationship) as part of onboarding.
Multi-domain administration
Mailboxes across multiple client domains are administered from a single relationship with IT KORR, rather than requiring a separate account or contract per domain.
Spam and deliverability management
Spam filtering and sender reputation are actively managed rather than left to default settings, which is where most deliverability problems in ad hoc mail setups originate.

Documentation, Evidence & Continuous Review
Per-domain authentication records
SPF, DKIM, and DMARC configuration is documented per domain, not assumed correct by default.
Migration and onboarding records
What was migrated, when, and from which source is recorded for every client domain onboarded.
Evidence your clients can use in their own audits
Documented per-domain authentication and onboarding records are retrievable if one of your clients is asked for them during their own compliance review or cyber-insurance renewal, not just internal records IT KORR keeps for its own purposes.
Frequently Asked Questions
Common Questions
Is this a formal reseller partner program with tiers or margins?
No. This describes hosted email as an ordinary IT KORR service — some buyers happen to be IT companies and consultants who provision mailboxes for their own clients on it. There is no tiered partner program, minimum commitment, or application process.
What email platform do you host on?
SmarterMail, a dedicated business email platform. It is not a resold consumer inbox and not Microsoft 365 or Google Workspace.
Can you migrate our clients from their current email?
Yes — migration from a legacy on-premises mail server, a consumer email setup, or a previous hosting relationship is part of onboarding.
Do you handle SPF, DKIM, and DMARC setup?
Yes, per domain, at setup — not left to default configuration. Deliverability depends on this being done correctly from the start.
Can we manage mailboxes for multiple client domains under one relationship?
Yes — mailbox administration across multiple client domains is handled through a single relationship with IT KORR rather than a separate account per domain.
Do you also host email directly for a single business, not as a reseller?
Hosted email is part of IT KORR's broader managed IT and infrastructure work for a single organization as well; this page describes the multi-domain, reseller-facing side of that same underlying service.
What happens to support as our client mailbox count grows?
Mailbox administration, password resets, and spam-filter tuning are handled on an ongoing basis as part of the relationship, not re-scoped every time a mailbox is added.
Is there a minimum number of domains or mailboxes to get started?
There is no published minimum, but this is built for an organization already managing, or expecting to grow, mailboxes across multiple client domains, not a one-off single-mailbox signup. Talk to us about where your client base is today.
