Dovel

Dovel is a self‑hostable SMTP server that handles both sending and receiving email using a straightforward configuration file. It operates without requiring a subscription or paid tier, and its source code is available under the LGPL‑3.0 license, allowing users to modify and redistribute it freely. The server is positioned as a stable component for managing email traffic in environments where a lightweight, configurable solution is needed.

In addition to core SMTP functionality, Dovel offers an optional web interface that lets users browse stored messages through a browser. This interface provides a simple way to view and manage email content without needing external mail clients. The web UI is not mandatory; the server can run solely via its configuration file for headless deployments.

The project targets individuals or organizations that want to run their own mail server with minimal setup and open‑source transparency. Its design emphasizes ease of configuration, self‑hosting, and the ability to inspect emails directly via the built‑in web portal.
