Sending email with ASP.NET 2.0

[shapper]

Hello,

I created an ASP.NET 2.0 custom control which includes various
TextBoxes, Labels and a button.
Basically is a contact form. When the button is pressed the values are
sent by email.

I want to use the mailSettings values in my Web.Config file.

Everything works fine if I use in my bSubmit function:

smtpClient.Host = "mail.domain.co m"
smtpClient.Port = "25"
smtpClient.UseD efaultCredentia ls = False
smtpClient.Cred entials = New
Net.NetworkCred ential("us**@do main.com", "password")
smtpClient.Deli veryMethod =
System.Net.Mail .SmtpDeliveryMe thod.Network

But if I don't include this code I get the error:

System.Net.Mail .SmtpFailedReci pientException: Mailbox unavailable. The
server response was: No such user here at
System.Net.Mail .SmtpTransport. SendMail(MailAd dress sender,
MailAddressColl ection recipients, String deliveryNotify,
SmtpFailedRecip ientException& exception) at
System.Net.Mail .SmtpClient.Sen d(MailMessage message) at
MyNamespace.Web .UI.Form.Contac t.bSubmit_Click (Object sender, EventArgs
e)

Shouldn't it be using the Web.Config values?
And if yes, why am I getting an error if the values are the same:

<system.net>
<mailSettings >
<smtp deliveryMethod = "network">
<network
defaultCredenti als = "true"
host = "mail.domain.co m"
password = "password"
port = "25"

userName = "us**@domain.co m" />
</smtp>
</mailSettings>
</system.net>

My bSubmit_Click function, inside my custom control, is the following:

Private Sub bSubmit_Click(B yVal sender As Object, ByVal e As
System.EventArg s) Handles bSubmit.Click

' Create new mail message
Dim message As New System.Net.Mail .MailMessage

' Define mail message properties
With message

' Define various properties
.To.Add(New System.Net.Mail .MailAddress(Me .ToAddress,
Me.ToName))
.Body = tbMessage.Text
.IsBodyHtml = True

' Define fromMailAddress
If Me.NameVisible Then
.From = New System.Net.Mail .MailAddress(tb Email.Text,
tbName.Text)
Else
.From = New System.Net.Mail .MailAddress(tb Email.Text)
End If

' Define subject
If Me.SubjectVisib le Then
.Subject = tbSubject.Text
End If

End With

' Define a new mail SMTP client
Dim smtpClient As New System.Net.Mail .SmtpClient

' Send the mail message and define sent property
Try

' Send the mail message
smtpClient.Send (message)

' Define sent property
Me.Sent = True

Catch ex As Exception

' Define sent property
Me.Sent = False

End Try

' Raise the OnFormSubmited event
RaiseEvent FormSubmited(Me , EventArgs.Empty )

End Sub

Thanks,
Miguel
