    vb 2005 email

    Trying to send email via vb 2005 win form. I'm able to send email out via Outlook express from this account and I verified everything 100 times, I don't think it's my host email server.
    I can't figure out what I'm doing wrong.
    Any help?

    I've got this code

    Private Sub btnSend_Click(B yVal sender As System.Object, ByVal e As System.EventArg s) Handles btnSend.Click
    Dim EMsg As New System.Net.Mail .MailMessage
    EMsg.From = New MailAddress("To ny@ValidAddress .com")
    EMsg.To.Add("To ny@ValidAddress .com")
    EMsg.Subject = "this is a test email"
    EMsg.Body = "this is the body of the email"
    'EMsg.IsBodyHtm l = True
    'send the message
    Dim smtp As New SmtpClient("htt p://mail.ValidAddre ss.com")
    smtp.Credential s = New Net.NetworkCred ential("Tony@Va lidAddress.com" , "ValidPassword" , "mail.ValidAddr ess.com")
    Try
    smtp.Send(EMsg)
    Catch ex As Exception
    ' MsgBox(ex.ToStr ing)
    txtMessage.Text = ex.ToString
    End Try
    End Sub

    I get this Error

    System.Net.Mail .SmtpException: Failure sending mail. ---> System.IO.IOExc eption: Unable to read data from the transport connection: net_io_connecti onclosed.

      Tony,

      You smtp server is wrong it should be something like this.

      Dim smtp As New SmtpClient("mai l.ValidAddress. com")
      smtp.Credential s = New Net.NetworkCred ential("Tony@Va lidAddress.com" ,
      "ValidPassword" , "mail.ValidAddr ess.com")
