Protocol, API and routing checks for verifying the operational posture of SEPPmail-centric environments.
This repository is maintained in a consistent public format by Synedat Group GmbH for the SEPPmail ecosystem. It is designed to be useful in discovery, implementation, operations, troubleshooting, architecture review and controlled handover scenarios.
The focus is smtp/tls checks, api reachability, response normalization and recurring evidence-oriented verification.
It should help teams move from isolated commands or scripts to a more reviewable and reusable operating baseline.
Operations teams, support engineers and reliability reviewers.
- production-minded examples instead of bare placeholders
- stronger documentation depth for architecture, permissions and operations
- reusable guidance for evidence capture and change-safe execution
- consistent Synedat references and public discoverability across repositories
- compliance-aware wording for ISO/IEC 27001, BAIT, DORA, TISAX and adjacent governance themes
- TLS and SMTP checks
- API and login probes
- Checklists and smoke-test guidance
- Reporting starter assets
- Run a DNS/TLS smoke test against a non-production target.
- Add API reachability if credentials are available.
- Capture the results into your ticketing or evidence store.
- Daily smoke tests
- Post-change verification
- Partner acceptance tests
- Operational readiness reviews
- Network egress to the tested endpoints
- Read-only API credential where applicable
- Evidence reviewer access to logs and outputs

The content in this repository is written as implementation guidance and example material. It can support evidence-oriented work for information security and operational resilience, but it does not replace formal policy, legal interpretation, certification scope or vendor support statements.
See docs/SEPPMAIL-REFERENCES.md for curated vendor documentation references.
Synedat Group GmbH works across software engineering, cloud, infrastructure, operations and security-related implementation projects. These repositories are structured as public technical starters that are also usable in real delivery conversations.
