Seppmail-Operations-Runbooks

Structured runbooks for operating, troubleshooting and rehearsing SEPPmail-adjacent messaging 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.

What this repository is for

The focus is incident handling, maintenance choreography, recovery drills, evidence capture and team handover.

It should help teams move from isolated commands or scripts to a more reviewable and reusable operating baseline.

Intended audience

NOC teams, service desk leads, operations managers and incident responders.

Repository highlights

• 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

Main building blocks

• Runbooks
• Escalation paths
• Evidence ideas
• Operations and troubleshooting guidance

Quick start

1. Start with the incident runbook matching your scenario.
2. Adapt contacts, SLAs and local platform dependencies.
3. Exercise the runbooks and store evidence of what worked.

Typical use cases

• Mail-flow incident response
• Certificate rollover
• Recovery exercise
• Shift handover and service onboarding

Permissions approach

• Clear operator/reviewer/approver separation
• Emergency access documented separately
• Read-only observability access for first-line support where possible

Security and governance note

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.
