System.Net.Mail.SmtpClient.Send Problem

This box sends email all the time with a localhost smtp address on .NET 1.1
code framework, fails with the 2.0 API. Any thoughts?

Exception:

   at System.Net.Mail.SmtpClient.Send(MailMessage message)
   at csxlib.SmtpMessage.TestSend() in F:\Projects\Visual Studio 2005\csxlib
v 0.9.7\SmtpMessage.vb:line 124
   at Mail_Test.Module1.Main() in F:\Projects\Visual Studio 2005\Mail
Test\Mail Test\Mail Test\Module1.vb:line 9
   at System.AppDomain.nExecuteAssembly(Assembly assembly, String[] args)
   at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence
assemblySecurity, String[] args)

   at System.Threading.ThreadHelper.ThreadStart_Context(Object state)
   at System.Threading.ExecutionContext.Run(ExecutionContext
executionContext, ContextCallback callback, Object state)
   at System.Threading.ThreadHelper.ThreadStart()"

Here is the code:

    Public Sub TestSend()
        Dim client As SmtpClient = New SmtpClient("localhost")
         Dim froom As MailAddress = New MailAddress***@d.com", "c",
System.Text.Encoding.UTF8)
        ' Set destinations for the e-mail message.
        Dim too As MailAddress = New MailAddress***@b.com")
        ' Specify the message content.
        Dim message As MailMessage = New MailMessage(froom, too)
        message.Body = "This is a test e-mail message sent by an
application. "
        ' Include some non-ASCII characters in body and subject.

        message.Body += Environment.NewLine + ">>>>>>>>>>>>>>>>>>>"
        message.BodyEncoding = System.Text.Encoding.UTF8
        message.Subject = "test message 1" + "<<<<<<<<<<<<<<<<"
        message.SubjectEncoding = System.Text.Encoding.UTF8
         client.Send(message)

        message.Dispose()

    End Sub

I have a complete 1.1 and 2.0 email send code you can download at:

The syntax of 2.0 is definately different.

Please post (here) if you figure out what it was.
