smpt client not being resolved.

I have been working through your book and I am currently having trouble getting the page to send me an email when it loads. (page 310 Chap 4).

I have an email address set up with my domain and I can send and receive emails with it so I know that it is configured correctly and works however when I reference the smpt client it is generating errors I believe.

The error is:
"The remote name could not be resolved: 'smtp.parkerdsgn.com'"

And the stack trace is:

Code:

[WebException: The remote name could not be resolved: 'smtp.parkerdsgn.com']
   System.Net.ServicePoint.GetConnection(PooledStream PooledStream, Object owner, Boolean async, IPAddress& address, Socket& abortSocket, Socket& abortSocket6, Int32 timeout) +5421675

   System.Net.Mail.SmtpClient.Send(MailMessage message) +1213

[SmtpException: Failure sending mail.]
   System.Net.Mail.SmtpClient.Send(MailMessage message) +1531
   Email.Page_Load(Object sender, EventArgs e) in C:\BegASPNET\Site\Demos\Email.aspx.vb:14
   System.Web.UI.Control.OnLoad(EventArgs e) +99
   System.Web.UI.Control.LoadRecursive() +50
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +627

But my smtp server is smtp.parkerdsgn.com so I am not sure whats wrong?

The code I have in my vb file is:

Code:

   Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim myMessage As MailMessage = New MailMessage()
        myMessage.Subject = "Test Message"
        myMessage.Body = "Hello World, from Will"
        myMessage.From = New MailAddress("[email protected]", "xxxxxx")
        myMessage.To.Add(New MailAddress("[email protected]", "xxxx"))

        Dim mySmtpClient = New SmtpClient()
        mySmtpClient.Send(myMessage)

Any help would be good, cheers.

Are you sure you're using the smtp server you mentioned below and not the one from your ISP? The fact that you have a domain and an associaetd e-mail address doesn't mean you also have an SMTP server. I tried resolving this address and didn't get back an IP address either./

Look into your mail client and see what SMTP server it uses. It may very well be different from what you posted here.

Hope this helps,

I checked my settings I have configured in Mozilla thunderbird and it says my outgoing server (SMTP) is mail.parkerdsgn.com and the server name is my servers ip address.

'smtp.parkerdsgn.com' != 'mail.parkerdsgn.com'

Maybe you're just using the wrong server name?

Thanks that worked.

I thought I had to have smtp infront of the server name so I was just replacing mail with smtp. I see now that I don't have to do that.

Thanks again for your help.
