Hi,

I tried to send email with these codes but there is a run time error when I tried to send the email. Is the problem related with the smtpserver?

 Try
                Dim Message As System.Web.Mail.MailMessage = New System.Web.Mail.MailMessage
            Message.To = "@yahoo.com"
            Message.From = "a@yahoo.com"
            Message.Subject = "nothing"
            Message.Body = "nothing"
            Try
                Dim smtp As System.Web.Mail.SmtpMail
                smtp.SmtpServer = "mail.i.net.au"
                smtp.Send("a@yahoo.com", "a@yahoo.com", "n", "n")
                'System.Web.Mail.SmtpMail.Send(Message)
                Response.Write("success")
            Catch
                Response.Write("error") -> this error message was displayed
            End Try
        Catch
                ' Display usage instructions if error in arguments.
            Response.Write("error2")
            End Try

It's hard to say what the error is. How about catching the error exception and printing out the message so you can see the details?

           Catch e As System.Exception
                Response.Write(e.Message)

The error says 'Could not access 'CDO.Message' object.'

Hi,

I just tried it at home (the first error was shown when I tried it at my school's PC). It said,

System.Web.HttpException: Could not access 'CDO.Message' object. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x8004020F): The server rejected one or more recipient addresses. The server response was: 550 not local host yahoo.com, not a gateway --- End of inner exception stack trace --- at System.RuntimeType.InvokeDispMethod(String name, BindingFlags invokeAttr, Object target, Object[] args, Boolean[] byrefModifiers, Int32 culture, String[] namedParameters) at System.RuntimeType.InvokeMember(String name, BindingFlags invokeAttr, Binder binder, Object target, Object[] args, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParameters) at System.Web.Mail.LateBoundAccessHelper.CallMethod(O bject obj, String methodName, Object[] args) --- End of inner exception stack trace --- at System.Web.Mail.LateBoundAccessHelper.CallMethod(O bject obj, String methodName, Object[] args) at System.Web.Mail.CdoSysHelper.Send(MailMessage message) at System.Web.Mail.CdoSysHelper.Send(String from, String to, String subject, String messageText) at System.Web.Mail.SmtpMail.Send(String from, String to, String subject, String messageText) at sandownregency.com.au.WebForm1.Page_Load(Object sender, EventArgs e)
what is exactly the fault?

that's the exact fault. It's right there.... your email server is not a gateway at school and won't let you use a non-local email address.

yea, i just figured it out. I tried to use my client's email as the receiver and it works(my client's email is on the mail server) (but I haven't checked whether my email was actually really sent, because I forgot my client's email password). Why does the server (mail.i.net.au) does not want to send any email outside its 'boundary'?

Becuase it is configured correctly to prevent spammers from using it as a gateway to flood the internet with spam. If every email server was configured properly (like this) we would find the volume of spam would plummet.

Hi
I also got this problem. but this prob come due to access permission of your smtp server.
the program is unable to access the smtp server. so it's better to configure your local server and test it out.

your code is absolutely fine

No problem such as
