MailWizz Engineering
Operational documentation for deploying and running MailWizz responsibly.
Production MailWizz Installation
Plan and deploy MailWizz with a safe application, database, web-server, and cron baseline.
MailWizz and PowerMTA Integration
Connect delivery servers, map identities, process bounces, and validate end-to-end flow.
MailWizz and Postfix Integration
Use authenticated SMTP or local relay designs while preserving separation of responsibilities.
Delivery Server Architecture
Design delivery servers by customer, stream, provider, IP pool, and operational risk.
Bounce Server Configuration
Create, test, monitor, and troubleshoot IMAP/POP3 bounce processing.
Feedback Loop Processing
Ingest complaint reports, suppress recipients, and retain auditable evidence.
Cron Job Operations
Install, validate, monitor, and recover MailWizz cron jobs without duplicate execution.
Campaign Queue Management
Understand campaign generation, sending, pauses, retries, and backlog recovery.
Database Operations
Protect MySQL/MariaDB performance, backups, indexes, and maintenance workflows.
Web Server and PHP Tuning
Tune PHP-FPM, OPcache, Nginx or Apache for predictable application performance.
Customer Isolation
Separate permissions, quotas, delivery servers, sending domains, and abuse risk.
Sending Domains and Authentication
Deploy SPF, DKIM, DMARC, tracking domains, and return-path identities correctly.
Tracking Domain Design
Configure HTTPS tracking domains, DNS, redirects, certificates, and ownership.
API Security
Protect API keys, rate-limit automation, log access, and rotate credentials safely.
Backup and Restore
Create recoverable backups of files, databases, encryption keys, and cron configuration.
Safe Upgrade Runbook
Prepare, stage, execute, validate, and roll back MailWizz upgrades.
Monitoring and Observability
Track cron freshness, queue depth, campaign velocity, bounce ingestion, and SMTP failures.
Abuse Prevention
Control imports, content, sender identities, complaint rates, and emergency suspension.
Multi-Node Deployment
Separate web, database, cron, queue, and SMTP workloads for growth and fault isolation.
Capacity Planning
Estimate application, queue, database, and SMTP capacity from real campaign behavior.
Warm-Up Workflows
Model ramp-up plans without confusing MailWizz schedules with provider reputation controls.
Reporting and Exports
Create reliable operational reports while avoiding heavy production queries.
MailWizz Security Hardening
Reduce attack surface across application, filesystem, PHP, database, and SMTP integrations.
MailWizz Server Migration
Move the application and database with controlled DNS, cron, queue, and delivery-server cutover.
