   Posthorn, self-hosted mail gateway▲83

   Introducing Posthorn, a self hosted email gateway. One docker container (or Go binary) between every self hosted app on your VPS and your transactional email provider.

Implementing this reliably—handling retries, monitoring, scaling, providing a decent dev experience for consumers, and managing tenants—becomes a significant, recurring engineering task that distracts from core product development. We built Outpost to offload that complexity. Outpost delivers events via…
