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(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSend.Click
Dim EMsg As New System.Net.Mail.MailMessage
EMsg.From = New MailAddress("To**@ValidAddress.com")
EMsg.To.Add("To**@ValidAddress.com")
EMsg.Subject = "this is a test email"
EMsg.Body = "this is the body of the email"
'EMsg.IsBodyHtml = True
'send the message
Dim smtp As New SmtpClient("http://mail.ValidAddress.com")
smtp.Credentials = New Net.NetworkCredential("To**@ValidAddress.com", "ValidPassword", "mail.ValidAddress.com")
Try
smtp.Send(EMsg)
Catch ex As Exception
' MsgBox(ex.ToString)
txtMessage.Text = ex.ToString
End Try
End Sub
I get this Error
System.Net.Mail.SmtpException: Failure sending mail. ---> System.IO.IOException: Unable to read data from the transport connection: net_io_connectionclosed.
