The server is written in .NET and contains 100% managed code, which makes it more reliable, efficient and fast.

It runs on any Windows server, which has .NET Framework 4.8.

By default, the server uses the SQLite database engine, but for heavier loads, we recommend using Microsoft SQL Server/SQL Server Express. The database engine can be converted with a single mouse click in the Mail Server UI.

The Server is constantly updated. Check our List of Changes regularly.

Feel free to evaluate the server for 30 days. It will be issued by our validation server when it first runs. Download it now.
