A C# console app that simulates an smtp server and save emails as html files. This is a very lightweight tool and therefore does not contain all the features of a full-fledged smtp server.
The source code is setup as a Visual Studio 2010 solution and does not have any external dependencies outside of Microsoft's .NET 4 Framework
The base source for FakeSmtp comes from various free sources available on the net (sorry, it was awhile ago and I didn't keep track) combined with some new features, such as the saving of each email to a html file.
FakeSmtp is very easy to use, just double click the executable or run it from a command line. There are no command line options.
The tool listens on port 25 for email messages.
