    {
        // Load HTML message from file.
        MailMessage message = new MailMessage();
        message.LoadMessage(@"C:\message.eml");

        Processor htmlProcessor = new Processor();

        htmlProcessor.Dom.OuterHtml = message.BodyHtmlText;

        // Get rules for removing all uneasy things (such as scripts) from the body.
        RuleSet rules = RuleSet.GetSafeHtmlRules();

        // Process the rules and display the results.
        Console.WriteLine(htmlProcessor.Dom.ProcessToString(rules, null));
