Problem Sending Mail

Hi!

This is the code I have for sending mail-

vb.net Syntax (Toggle Plain Text) 
  1.  
  2. Imports System.Web.Mail
  3.  
  4. Public Class Form1
  5.  
  6.  
  7.  
  8.  
  9.     Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  10.  
  11.     End Sub
  12.  
  13.     Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
  14.         Dim Mailmsg As New System.Web.Mail.MailMessage()
  15.         SmtpMail.SmtpServer = "mysmtpserver"
  16.         Mailmsg.To = "recepient@domain.com"
  17.  
  18.         Mailmsg.From = "\" & "foo" & "\ <" & "bar@domain.com" & ">"
  19.         Mailmsg.Subject = "Sending a test mail"
  20.  
  21.         'Mail Body
  22.         Mailmsg.Body = "This is a test message"
  23.  
  24.         Mailmsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1") 'basic authentication
  25.         Mailmsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "myusername") 'set your username here
  26.         Mailmsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "mypassword") 'set your password here
  27.         Mailmsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", "26") 'Put port number here
  28.  
  29.  
  30.  
  31.  
  32.         Try
  33.             SmtpMail.Send(Mailmsg)
  34.         Catch ex As Exception
  35.             'MsgBox(ex.ToString)
  36.             Me.TextBox1.Text = ex.ToString
  37.         End Try
  38.  
  39.  
  40.  
  41.     End Sub
  42. End Class


The error message I get is-

System.Web.HttpException: The transport failed to connect to the server.
---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x80040213): The transport failed to connect to the server.

Tried to google, but no luck.

Any ideas?

If I try port 25, I get this message-

System.Web.HttpException: The message could not be sent to the SMTP server. The transport error code was 0x80040217. The server response was not available

VB.NET Syntax (Toggle Plain Text) 
  1. SmtpMail.SmtpServer = "mysmtpserver"
mysmtpserver, did you stated this value for testingpurposes? It should be a real smtpserver like mail.yourcompany.com.....

Regards,

[edit]
Be aware that most smtp servers don't respond on RELAY. Systemadministrators block relaying their smtp server

I did put valid values in the actual code I used, just did not want to post it here.

Have used a correct smtp server, username, password - sure of that

Okay, just for asking.....

Check this site, it's a good reference for programming-help. Try the simple example and if that works, extend it piece by piece.
Let me know if it worked....

I guess I've specifically used this-

The server requires authentication.

It should work with the fields.add() like you mentioned before. Did you also checked if your firewall blocks ports 25? If so, port 2525 might do the job....

No luck with port 2525 either, have disabled my firewall too.

Any other troubleshooting steps?

Thanks a lot for your ideas.
