The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.

  • Organizations that don't train their talents on key topics see their competitiveness drop.

  • Every quarter without training is a gap widening with competitors who invest.

  • The cost of inaction quickly exceeds that of well-targeted training.

Program

Module 1Advanced DKIM Fundamentals: Cryptography and Key Generation (OpenDKIM, Postfix)

Dive into advanced DKIM key pair generation with OpenDKIM and Postfix, applied to massive supply chain tracking emails, create multi-selector signatures for specific logistics segments, test real-time DNS propagation using dig and nslookup, analyze failing DKIM headers on real transport fraud cases, produce a custom DKIM certificate for your enterprise domain, practical exercises on remote virtual servers.

Module 2Multi-Domain DKIM Configuration: Supply Chain Integration (Exim, Zimbra)

Configure DKIM for multiple domains in supply chain with Exim and Zimbra, integrate custom macros for intelligent transport routing, simulate high-volume logistics email flows with DKIM injection, debug rejections via advanced logs and tools like dkimvalidator, apply selective policies per stock subdomain, generate DKIM compliance reports for internal audits, implement automated key rotations for high enterprise availability.

Module 3DKIM Optimization in Hybrid Environments: Cloud and On-Premise (AWS SES, SendGrid)

Optimize DKIM in hybrid supply chain setups via AWS SES and SendGrid, align signatures with strict DMARC for transport anti-spoofing protection, test scalability on 10,000 simulated emails per hour, integrate DKIM with logistics APIs for secure tracking, analyze performance with RSA-SHA256 vs ED25519 metrics, deploy DKIM monitoring via Prometheus and Grafana, produce troubleshooting playbooks for logistics teams, exercises on remote Kubernetes clusters.

Module 4DKIM Audits and Troubleshooting: Advanced Supply Chain Cases (Audit Deliverables)

Conduct complete DKIM audits on real supply chain infrastructures, identify leaks via DKIM-FAILURE in Postfix/Exim logs, remediate failing alignments with tools like dmarcly, simulate BEC attacks on transport emails to validate robustness, generate certifying reports with DKIM scores for management committees, implement Ansible automations for DKIM deployments, conclude with final project: end-to-end logistics flow security, delivery of ready-to-use templates.

Evaluation method

  • Advanced technical quiz on DKIM and associated protocols
  • Practical case study: DKIM audit on simulated supply chain flows
  • Final certifying project: multi-domain DKIM implementation with report

Learning method

  • Active pedagogy with 70% hands-on practice on secure remote labs
  • Real cases from logistics and supply chain companies
  • Individualized exercises adapted to Advanced level
  • 6-month post-training support via dedicated platform

Methods, materials and delivery

The DKIM Training - Securing Advanced Supply Chain Emails program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the DKIM Training - Securing Advanced Supply Chain Emails program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the DKIM Training - Securing Advanced Supply Chain Emails program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
