netDumbster is a .Net Fake SMTP Server clone of the popular Dumbster.

netDumbster is based on the API of nDumbster (http://ndumbster.sourceforge.net/default.html) and the nice C# Email Server (CSES) written by Eric Daugherty.

Create a netDumbster Server instance:

using var server = SimpleSmtpServer.Start(port);

Check received email count:

var count = server.ReceivedEmailCount

Get the body of the first email received:

var smtpMessage = server.ReceivedEmail[0];
var body = smtpMessage.MessageParts[0].BodyData

Subscribe to the message received event:

server.MessageReceived += (sender, args) =>
    {
        // Get message body.
        var body = args.Message.MessageParts[0].BodyData;
    };
