About Jobtome
Jobtome is a global job search engine operating in multiple countries, connecting millions of job seekers with employment opportunities. Their platform aggregates job listings from thousands of sources and delivers personalized job alerts via email to their user base.
Email is the primary communication channel for Jobtome, powering daily job alerts, account notifications, and marketing campaigns. As their user base grew, managing the sprawling email infrastructure became increasingly complex and costly.
The Challenge
Sprawling Infrastructure, Rising Costs
Jobtome's email infrastructure had grown organically over years, resulting in 30 separate Postfix installations spread across multiple servers. Each installation required individual configuration, monitoring, and maintenance — consuming an enormous amount of engineering time.
- close30 separate Postfix servers requiring individual management and configuration
- closeHigh operational overhead with engineers spending hours on routine maintenance
- closeInconsistent delivery policies across different server instances
- closeDifficult to scale — adding capacity meant provisioning and configuring new servers
- closeLimited centralized monitoring made it hard to track delivery performance
- closeFrequent configuration drift between server instances causing inconsistent behavior
The Solution
Consolidating to a Single MTA
Jobtome replaced their entire Postfix fleet with a single PostMTA instance built on KumoMTA. The consolidation eliminated the management burden of 30 separate installations while delivering superior throughput and reliability.
PostMTA's architecture was designed for exactly this scenario — replacing fleets of legacy MTAs with a single, high-performance instance. The built-in queue management, real-time monitoring, and comprehensive API gave Jobtome more control with far less complexity.

Pre- vs. Post-Migration Comparison
| Metric | Before (30 Postfix) | After (1 PostMTA) | Improvement |
|---|---|---|---|
| Server Count | 30 | 1 | 97% fewer |
| Management Hours/Week | ~20 hrs | ~2 hrs | 90% reduction |
| Delivery Throughput | Baseline | 3x | Significant |
| Configuration Drift | Common | None | Eliminated |
| Monitoring Complexity | High | Low | Centralized |
“Managing 30 Postfix servers was a nightmare. Every server needed individual attention, and configuration drift was a constant battle. PostMTA's consolidation gave us back hours of engineering time every week while actually improving our delivery performance. It was the best infrastructure decision we've made.”
