On-Premise
Customer data centre. Full perimeter control. Air-gap compatible.
SEVOCOMM MTA is a European, sovereign mail platform for organizations that refuse to outsource their email infrastructure. Full control over deployment, data location, and operational posture — with monitoring, security, and TLS trust built in from day one.
Scannable in seconds. Defensible in an audit.
Engineered in Europe. Aligned with strict data-protection expectations from day one.
No forced cloud tenancy. No vendor-controlled routing. No hidden dependencies.
You decide where it runs, where the data lives, and who can touch it. End to end.
On-premise, private cloud, public cloud, or ISP infrastructure — identical behavior.
Monitoring-first design. Metrics, dashboards, and alerting ship with the product.
Native MTA-STS and TLSRPT. Continuous visibility into real-world delivery security.
Modern mail stacks quietly pull organizations into dependencies they never agreed to: opaque routing, per-seat pricing curves, tenant boundaries enforced by the vendor, and data residency expressed as a contract clause instead of an architectural fact.
SaaS mail providers bind routing, identity, and policy into a single non-portable surface. Exit is expensive. Change is slow.
Mail is processed, queued, and logged in locations your audit team can't reach. "Cloud" is not the same as controlled.
TLS is reported as binary. Downgrades go unnoticed. Deliverability problems surface days after they mattered.
Data location is a promise in a DPA, not an architectural guarantee. Regulators increasingly reject that distinction.
Tier-1 tickets route to the vendor. Root cause arrives later — if at all. You carry the risk; someone else carries the console.
SEVOCOMM MTA reverses the arrangement.
See how deployment works →The single most important architectural guarantee of SEVOCOMM MTA: the deployment model is not imposed. It is chosen — by the customer, for the customer, with no vendor-managed layer in between.
Customer data centre. Full perimeter control. Air-gap compatible.
Dedicated, sovereign region. Customer-managed tenancy boundary.
AWS, Azure, GCP, Hetzner, OVH — infrastructure you already control.
Multi-tenant, white-label ready, operator-scale provisioning.
“Deployment is fully decided by the customer.”
— Core product principle · Non-negotiable
A modern mail engine structured around three design principles: architectural modularity, first-class observability, and unconditional portability — no forced SaaS layer, no vendor-controlled routing.
High-performance SMTP front-end with policy hooks, DKIM signing, content filtering, and full queue visibility. Standards-compliant IMAP4, POP3, and Submission. Postfix- and Dovecot-compatible for drop-in interoperability.
DKIM, SPF, DMARC with aggregate-report ingestion. RBL integration, abuse-pattern detection, and TLS 1.2 / 1.3 enforcement built into the pipeline — every message, every hop.
Prometheus-compatible metrics, native dashboards, webhook dispatch, and live queue/TLS/health telemetry. Monitoring is a foundational subsystem — not an optional tier.
Multi-domain, multi-tenant control plane with role-based access, audit logging, DNS helper, and certificate automation. Every UI action is reachable via REST API.
Open standards only: SMTP, IMAP, POP, CalDAV, CardDAV, MTA-STS, TLSRPT, DKIM, SPF, DMARC. No proprietary wrappers. Fits any SOC, SIEM, or observability stack already in place.
Real screenshots from production — every view below is shipping functionality.
Most platforms treat TLS as binary — either it handshakes or it doesn't. SEVOCOMM MTA treats TLS as an ongoing intelligence signal, continuously evaluating how your mail actually traverses the public network.
The difference between “encrypted in transit” and “provably encrypted in transit” is the difference between a marketing claim and an operational fact.

The platform was designed with operational visibility as a foundational constraint. Metrics, dashboards, and alerting ship with every deployment — not as an optional integration tier, and never as a separate license.
Three concrete, executive-level results — not features in disguise.
Own the cost model. Forecast it. Defend it.
Less exposure. Less surprise. Less dependency.
Sovereignty by architecture, not by policy.
Same platform, three operational profiles. No feature gating that forces a “move up to the next tier” conversation.
Independence, cost control, predictable deployment.
Compliance, auditability, data sovereignty, internal control.
Multi-tenant, white-label ready, operator-scale visibility.
A compact technical summary for the people who will actually run it.
The six questions that come up in every first conversation.
SEVOCOMM MTA is a European-developed, sovereign mail platform designed for organizations that require full control over their email infrastructure, data location, and deployment model. It delivers enterprise-grade SMTP, IMAP, POP, security, and monitoring — without SaaS lock-in.
Deployment is fully decided by the customer. SEVOCOMM MTA runs identically on on-premise hardware, private cloud, public cloud (AWS, Azure, GCP, Hetzner, OVH) and ISP / telecom infrastructure. There is no vendor-managed SaaS layer and no forced tenancy.
SEVOCOMM MTA enforces TLS 1.2 and 1.3 with modern cipher suites only. DKIM, SPF and DMARC are built into the pipeline, including aggregate-report ingestion. MTA-STS and TLSRPT are native capabilities — together forming TLS Trust Intelligence with continuous visibility into real-world delivery security and downgrade attempts.
Yes. Full multi-tenant isolation, white-label branding per tenant, high-volume mail processing, per-tenant SLA reporting, and operator-scale provisioning APIs are first-class features — not enterprise-edition gating.
Because deployment is customer-controlled, data residency is an architectural choice rather than a contractual promise. Retention, legal hold, journaling and evidence export are built in, which supports GDPR, ISO 27001, and NIS2 programs and makes compliance auditable from first principles.
Yes. The SMTP engine is Postfix-compatible and IMAP/POP access is Dovecot-compatible, enabling drop-in interoperability during migration. Open standards — SMTP, IMAP, POP, CalDAV, CardDAV, DKIM, SPF, DMARC, MTA-STS, TLSRPT — are used throughout, with no proprietary wrappers.
Sovereignty, control, and independence are not add-on features — they are the reason SEVOCOMM MTA exists. If those outcomes match your posture, the next step is a direct conversation.
