Outlook Script to Check for Hidden Attachment

Question

I've got an outlook script which shows you the recipient and prompts the user "Are you sure you wish to send this e-mail to XXX?" However, we have an issue with a plugin we use to send secure files which prompts the user twice from the script instead of once. They tell me to loop through the items.Attachments property to check for a filename ending with ".sf". If it contains this then to abort my script. Can anyone tell me how to do this?

Private Sub Application_ItemSend _ (ByVal Item As Object, Cancel As Boolean)
Dim strMsg As String
Dim Atmt As Variant

If Item.Class = "43" Then
   For Each Atmt In Item.Attachments
       If Right(Atmt.FileName, 3) = ".sf" Then
          GoTo NonEmailError
       End If
   Next Atmt

   If Item.CC = "" Then
      strMsg = "To recipients: " & Item.To & vbCrLf & _
       "Are you sure you want to send this message?"
   Else
      strMsg = "To recipients: " & Item.To & vbCrLf & _
      "Cc recipients: " & Item.CC & vbCrLf & _
      "Bcc recipients: " & Item.BCC & vbCrLf & _
       "Are you sure you want to send this message?"
   End If
Else
    GoTo NonEmailError
End If

On Error GoTo NonEmailError

NonEmailError:
' The item being sent was not an e-mail and so don't prompt the user anything
Exit Sub

End Sub

You want a For Each loop in your script that loops through the attachment list. Something like the below. Note, this is pseudo-code. I haven't tried it:

For Each Atmt In item.Attachments
    If Right(Atmt.FileName, 3) = ".sf" Then
       --  Your code here
    EndIf
Next Atmt
