Reference material and migration helpers for older SEPPmail-oriented tooling and legacy integration patterns.
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 legacy script preservation, migration notes, compatibility mapping and retirement planning.
It should help teams move from isolated commands or scripts to a more reviewable and reusable operating baseline.
Operators handling brownfield estates, migration teams and technical 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
- Legacy scripts
- Auth and endpoint migration notes
- Mapping guidance
- Brownfield operations guidance
- Identify which scripts are still used in production.
- Map each script to a modern API or module pattern.
- Plan retirement, replacement or wrapper strategies.
- Brownfield estate review
- Migration planning
- Compatibility analysis
- Preservation of historical know-how
- Treat legacy credentials as sensitive and isolate them
- Use read-only accounts wherever possible
- Require review before reusing historical write operations

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.
