public static void CreateBccTestMessage(string server)
	MailAddress from = new MailAddress("", "Ben Miller");
	MailAddress to = new MailAddress("", "Jane Clayton");
	MailMessage message = new MailMessage(from, to);
	message.Subject = "Using the SmtpClient class.";
	message.Body = @"Using this feature, you can send an e-mail message from an application very easily.";
	MailAddress bcc = new MailAddress("");
	SmtpClient client = new SmtpClient(server);
	client.Credentials = CredentialCache.DefaultNetworkCredentials;
	Console.WriteLine("Sending an e-mail message to {0} and {1}.", 
	    to.DisplayName, message.Bcc.ToString());
    try {
    catch (Exception ex) {
      Console.WriteLine("Exception caught in CreateBccTestMessage(): {0}", 
                  ex.ToString() );
