Problems connecting to smtpserver

I have spent half a day trying to get this to work, I hope someone can help me out.
This is the code I am trying to run
Dim emailMessage As EmailMessage = New EmailMessage
emailMessage.FromAddress = New EmailAddress("myinternalemail@mycompany.com", "Charles Swann")
emailMessage.AddToAddress(New EmailAddress("myinternalemail@mycompany.com", "Odette de Crecy"))
emailMessage.Subject = "Missed you"
emailMessage.TextPart = New TextAttachment("Just checking where " & "you were last night." & Constants.vbCrLf & "Send me a note!" & Constants.vbCrLf & Constants.vbCrLf & "-Charles")
emailMessage.HtmlPart = New HtmlAttachment("<html><body>" & "<p>Just checking up on where you were last night.</p>" & Constants.vbCrLf & "<p>Send me a note!</p>" & Constants.vbCrLf & Constants.vbCrLf & "<p>-Charles</p></body></html>")
Dim oSmtpServer As SmtpServer = New SmtpServer("localhost")
emailMessage.Send(oSmtpServer)
I keep getting could not connect to (shows the ip address), when I trace it I get the error from the tcpip client that the software closed the connection.
If I use the following code using the same smtpserver
'Add the following code in a button click or link click
Dim mm As New Mail.MailMessage
mm.To = "jose.garcia@hbc.com"
mm.Cc = "jose.garcia@hbc.com"
mm.From = "jose.garcia@hbc.com"
mm.Subject = "Testing the Email through ASP.Net"
mm.BodyFormat = MailFormat.Html
mm.Body = "<h1>This is just a test mail. Looks like it passed</h1><br><table border='1'><tr><td>testing</td></tr></table>"
'Your ip address/ localweb server name
SmtpMail.SmtpServer.Insert(0, "localhost")
Try
SmtpMail.Send(mm)
Catch ex As Exception
Throw (ex)
End Try
All works fine.
I am not sure what I am missing with the use of this component.
Any ideas will be appreciated...
Thanks.

Hi-
Are you sure you have an SMTP server running on localhost? If you're getting a "could not connect" error, it's probably not running. If you are logging in to another machine, it could also mean that it's either a firewall or network problem.
An easy way to test it is to run telnet and log in to port 25, e.g. from a DOS prompt:
telnet localhost 25.
Cheers!
