Microsoft Outlook security delay

I use the following code to send emails.

   Private Sub SendOutlook(ByVal subject As String, ByVal toe As String, _
     ByVal body As String, ByVal from As String)
      Dim Appl As Object
      Dim out As Object
         Appl = CreateObject("Outlook.Application")
         out = Appl.CreateItem(0)
         With out
            .Subject = subject
            .To = toe
            .Body = body
            'to use html in the email instead of plain text
            'use .HTMLBody instead of .body
         End With
      Catch ex As Exception
         MsgBox("Error " & Err.Number & ": " & ex.Message, MsgBoxStyle.Critical, "Error")
      End Try
   End Sub 'SendOutlook

This works fine, but I send many in a do loop with different messages.
Microsoft Outlook displays a message:
     A program is automatically trying to send an e-mail on your behalf.
     Do you want to allow this?
There is a long pause between each e-mail sent before I can respond Yes.  How can I eliminate this check?

If you really want to use Outlook, you can automate the Yes by using a add-in:

But personnaly, I avoid using Outlook from applications. Have a look at the System.Web.Mail namespace that you can use even from Windows application.
using System.Web.Mail

MailMessage mail= new MailMessage();
mail.TO = "";
mail.From= "";
mail.subject ="subject";
myMessage.Body ="BODY";

SmtpMail.SmtpServer = "your smtp server";
Imports System.Web.Mail

Dim mesg As MailMessage = New MailMessage ()

mail.To = ""
mail.From = ""
mail.subject = "subject"
myMessage.Body = "BODY"

SmtpMail.SmtpServer = "your smtp server"

Sorry I wrote that in C#

I can't import System.Web.Mail.  Is there something missing in my VB?

To emoreau:
I don't care what method I use to send the e-mails.  The methods should be available to the users.  Perhaps I could automate the "YES" in outlook, but there is a 5-second pause before it comes up.  That is a poor solution, if there is a better way.
