Emailing Troubles

Hi there,
I am trying to send an email from a remote email server that requires email authentication (requires credentials to log into the webserver in order to send the email).
I have encountered the following error while trying to send an email:

"SocketException (0x274d): No connection could be made because the target machine actively refused it."

The code that generates the error is:

   Dim retval As Boolean
   retval = False
   Dim emailMessage As Net.Mail.MailMessage
   Dim body As String = compileEmailMessage()
 
   emailMessage = New Net.Mail.MailMessage("[e-mail]", "[e-mail]", "Title", body)
 
    Dim mailClient As New Net.Mail.SmtpClient
    Dim myCredentials As New System.Net.NetworkCredential("[e-mail]", "******")
 
     mailClient.Host = "mail.MyMailServer.ca"
     mailClient.UseDefaultCredentials = False
     mailClient.Credentials = myCredentials
    Try
          mailClient.Send(emailMessage)  '<-----Crashes on this line
          retval = True
     Catch ex As Exception
           retval = False
          lbl_debug.text = ex.Message + " " + ex.StackTrace
     End Try
 

Has anyone seen this error before or have any comments on how I could fix this error?

Thanks a lot for your help.

I figured it out thanks. I found out that the mail server doesn't run on the default port. Once I supplied the port everything worked fine.
