Our servers contain only 100% managed code (.NET), which makes it more reliable, efficient and fast.

Supported Windows versions are 2008 Server, Windows 7 or later (needs to run .NET 4.5 or higher);

By default, server uses SQLite database engine, but for heavier loads, we recommend to use Microsoft SQL server.  Version 2005 or higher is supported.  Express edition (which is free) should work fine too.  It can be downloaded from here.  If, at some point, you will decide to switch between SQLite and SQL server, it is pretty easy, but it may be time consuming, depending on the usage of your server.

Mail server comes with a free 30 day license. It will be issued by our validation server when you run it for first time.
