Service features

Security, storage, and deliverability designed for long-term use.

This page outlines the core features of NSATS Mail. Storage is unlimited without a fair-use limitation on stored email or attachments. Access is protected using SSL/TLS encrypted connections. The security architecture is designed to adopt post-quantum cryptography as standards evolve.

Feature summary

Unlimited storage

Mailbox capacity is unlimited. No fair-use limitation applies to stored email or attachments. Quotas are not used as a mechanism to force deletion.

Security controls

SSL/TLS encrypted connections protect access in transit. Post-quantum security architecture supports long-term resilience as cryptographic standards evolve.

Deliverability

Spam filtering reduces unsolicited mail. DKIM and DMARC support sender verification and help reduce spoofing.

Core features

Two service foundations are implemented as first-class features: unlimited storage and security architecture designed for future cryptographic standards.

Unlimited mailbox storage

Storage capacity is unlimited. This applies to stored messages and attachments and is not subject to a fair-use limitation on storage. The service is engineered to support continued mailbox growth without requiring users to manage quotas.

Storage policy applies to retention and capacity. Acceptable-use and anti-abuse controls remain in force for sending behavior, spam prevention, and account protection.

Post-quantum security architecture

Post-quantum indicates an architecture designed to adopt cryptographic methods intended to remain robust as future computing capabilities evolve. This approach reduces dependence on a single generation of cryptographic assumptions and supports long-term security posture.

Access protection and operational security controls remain active regardless of future cryptographic transitions, ensuring continuity of service and security controls.

Operational controls and user assurances

Key points that reduce ambiguity in security, storage, and deliverability.

Storage policy versus sending policy

“No fair-use limitation” applies specifically to storage and retention. This does not authorize unsolicited sending, bulk abuse, or policy violations. Anti-abuse enforcement and spam prevention remain active at all times.

Encrypted access (SSL/TLS)

SSL/TLS encrypted connections protect mailbox traffic and credentials in transit between user devices and NSATS Mail systems. This reduces exposure risk when accessing email across networks.

Sender verification (DKIM/DMARC)

DKIM and DMARC provide domain-based verification signals that assist recipient systems in identifying legitimate mail and reducing spoofing and impersonation attempts.
