+# Mailu Deployment Architecture for Bakery-IA Project
+
+## Executive Summary
+
+This document outlines the recommended architecture for deploying Mailu email services across development and production environments for the Bakery-IA project. The solution addresses DNSSEC validation requirements while maintaining consistency across different Kubernetes platforms.
+
+## Environment Overview
+
+### Development Environment
+- **Platform**: Kind (Kubernetes in Docker) or Colima
+- **Purpose**: Local development and testing
+- **Characteristics**: Ephemeral, single-node, resource-constrained
+
+### Production Environment
+- **Platform**: MicroK8s on Ubuntu VPS
+- **Purpose**: Production email services
+- **Characteristics**: Single-node or small cluster, persistent storage, production-grade reliability
+
+## Core Requirements
+
+1. **DNSSEC Validation**: Mailu v1.9+ requires DNSSEC-validating resolver
+2. **Cross-Environment Consistency**: Unified approach for dev and prod
+3. **Resource Efficiency**: Optimized for constrained environments
+4. **Reliability**: Production-grade availability and monitoring
+
+## Architectural Solution
+
+### Unified DNS Resolution Strategy
+
+**Recommended Approach**: Deploy Unbound as a dedicated DNSSEC-validating resolver pod in both environments
+
+#### Benefits:
+- ✅ Consistent behavior across dev and prod
+- ✅ Meets Mailu's DNSSEC requirements
+- ✅ Privacy-preserving (no external DNS queries)
+- ✅ Avoids rate-limiting from public DNS providers
+- ✅ Full control over DNS resolution
+
+### Implementation Components
+
+#### 1. Unbound Deployment Manifest
+
+```yaml
+# unbound.yaml - Cross-environment compatible

+
+#### 2. Mailu Configuration (values.yaml)
+
+```yaml
+# Production-tuned Mailu configuration
+dnsPolicy: None
+dnsConfig:
+  nameservers:
+    - "10.152.183.x"  # Replace with actual unbound service IP
+
+# Component-specific DNS configuration
+admin:
+  dnsPolicy: None

+      - "10.152.183.x"
+
+rspamd:
+  dnsPolicy: None
+  dnsConfig:
+    nameservers:
+      - "10.152.183.x"
+
+# Environment-specific configurations
+persistence:
+  enabled: true
+  # Development: use default storage class
+  # Production: use microk8s-hostpath or longhorn
+  storageClass: "standard"
+
+replicas: 1  # Increase in production as needed
+
+# Security settings
+secretKey: "generate-strong-key-here"
+
+# Ingress configuration
+# Use existing Bakery-IA ingress controller
+```
+
+### Environment-Specific Adaptations
+
+#### Development (Kind/Colima)
+
+**Optimizations:**
+- Use hostPath volumes for persistence
+- Reduce resource requests/limits
+- Disable or simplify monitoring
+- Use NodePort for external access
+
+**Deployment:**
+```bash
+# Apply unbound
+kubectl apply -f unbound.yaml
+
+# Get unbound service IP
+UNBOUND_IP=$(kubectl get svc unbound-dns -n mailu -o jsonpath='{.spec.clusterIP}')
+
+# Deploy Mailu with dev-specific values
+helm upgrade --install mailu mailu/mailu \
+  --namespace mailu \
+  -f values-dev.yaml \
+  --set dnsConfig.nameservers[0]=$UNBOUND_IP
+```
+
+#### Production (MicroK8s/Ubuntu)
+
+**Enhancements:**
+- Use Longhorn or OpenEBS for storage
+- Enable monitoring and logging
+- Configure proper ingress with TLS
+- Set up backup solutions
+
+**Deployment:**
+```bash
+# Enable required MicroK8s addons
+microk8s enable dns storage ingress metallb
+
+# Apply unbound
+kubectl apply -f unbound.yaml
+
+# Get unbound service IP
+UNBOUND_IP=$(kubectl get svc unbound-dns -n mailu -o jsonpath='{.spec.clusterIP}')
+
+# Deploy Mailu with production values
+helm upgrade --install mailu mailu/mailu \
+  --namespace mailu \
+  -f values-prod.yaml \
+  --set dnsConfig.nameservers[0]=$UNBOUND_IP
+```
+
+## Verification Procedures
+
+### DNSSEC Validation Test
+
+```bash
+# From within a Mailu pod
+kubectl exec -it -n mailu deploy/mailu-admin -- bash
+
+# Test DNSSEC validation
+dig @unbound-dns +short +dnssec +adflag example.org A
+
+# Should show AD flag in response
+```
+
+### Service Health Checks
+
+```bash
+# Check unbound service
+kubectl get pods -n mailu -l app=unbound
+kubectl logs -n mailu -l app=unbound
+
+# Check Mailu components
+kubectl get pods -n mailu
+kubectl logs -n mailu -l app.kubernetes.io/name=mailu
+```
+
+## Monitoring and Maintenance
+
+### Production Monitoring Setup
+
+```yaml
+# Example monitoring configuration for production
+apiVersion: monitoring.coreos.com/v1
+kind: ServiceMonitor
+metadata:
+  name: unbound-monitor
+  namespace: mailu
+spec:
+  selector:
+    matchLabels:
+      app: unbound
+  endpoints:
+  - port: dns-tcp
+    interval: 30s
+    path: /metrics
+```
+
+### Backup Strategy
+
+**Production:**
+- Daily Velero backups of Mailu namespace
+- Weekly database dumps
+- Monthly full cluster snapshots
+
+**Development:**
+- On-demand backups before major changes
+- Volume snapshots for critical data
+
+## Troubleshooting Guide
+
+### Common Issues and Solutions
+
+**Issue: DNSSEC validation failures**
+- Verify unbound pod logs
+- Check network policies
+- Test DNS resolution from within pods
+
+**Issue: Mailu pods failing to start**
+- Confirm DNS configuration in values.yaml
+- Verify unbound service is reachable
+- Check resource availability
+
+**Issue: Performance problems**
+- Monitor CPU/memory usage
+- Adjust resource limits
+- Consider scaling replicas
+
+## Migration Path
+
+### From Development to Production
+
+1. **Configuration Migration**
+   - Update storage class from hostPath to production storage
+   - Adjust resource requests/limits
+   - Enable monitoring and logging
+
+2. **Data Migration**
+   - Export development data
+   - Import into production environment
+   - Verify data integrity
+
+3. **DNS Configuration**
+   - Update DNS records to point to production
+   - Verify TLS certificates
+   - Test email delivery
+
+## Security Considerations
+
+### Production Security Hardening
+
+1. **Network Security**
+   - Implement network policies
+   - Restrict ingress/egress traffic
+   - Use TLS for all external communications
+
+2. **Access Control**
+   - Implement RBAC for Mailu namespace
+   - Restrict admin access
+   - Use strong authentication
+
+3. **Monitoring and Alerting**
+   - Set up anomaly detection
+   - Configure alert thresholds
+   - Implement log retention policies
+
+## Cost Optimization
+
+### Resource Management
+
+**Development:**
+- Use minimal resource allocations
+- Scale down when not in use
+- Clean up unused resources
+
+**Production:**
+- Right-size resource requests
+- Implement auto-scaling where possible
+- Monitor and optimize usage patterns
+
+## Conclusion
+
+This architecture provides a robust, consistent solution for deploying Mailu across development and production environments. By using Unbound as a dedicated DNSSEC-validating resolver, we ensure compliance with Mailu's requirements while maintaining flexibility and reliability across different Kubernetes platforms.
+
+The solution is designed to be:
+- **Consistent**: Same core architecture across environments
+- **Reliable**: Production-grade availability and monitoring
+- **Efficient**: Optimized resource usage
+- **Maintainable**: Clear documentation and troubleshooting guides
+
+This approach aligns with the Bakery-IA project's requirements for a secure, reliable email infrastructure that can be consistently deployed across different environments.
