unable to connect to the remote server while sending email

[Guest]

Hi,

I have created a windows application to send the emails. Following is the
code I am using.

Dim errMsg As String
Dim ToAddress As String
Dim FromAddress As String
Try
ToAddress = "(e-mail address removed)"
FromAddress = "(e-mail address removed)"
Dim mm As New MailMessage(FromAddress, ToAddress)

mm.Subject = "Test"
mm.Body = "Test Email"
mm.IsBodyHtml = False

Dim smtp As New SmtpClient
smtp.Send(mm)

Catch ex As Exception
errMsg = ex.InnerException.Message
End Try

In the app.config I specified
<system.net>
<mailSettings>
<smtp>
<network host ="myexchangeserveripaddress" />
</smtp>
</mailSettings>
</system.net>

I am running this code on windows vista. I am not sure if that is the issue.
If so how could I resolve that?

Thanks,

What is the problem? You'd get more (and better) assistance if you
specify what your problem is.

I put the error message in the subject. This is the detailed error message

System.Net.Mail.SmtpException - Failure sending mail.
InnerException - Unable to connect to Remote server.
No Connection could be made because the target machine actively
refused it.

Ah, I missed that.

With regards to your smtp server, perhaps it requires authentication?
