Set iMsg = CreateObject("CDO.Message")
Set iConf = CreateObject("CDO.Configuration")

iConf.Load -1 ' CDO Source Defaults
Set Flds = iConf.Fields
With Flds
.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 1
.Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = ""
.Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = ""
.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") _
= ""
.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
.Update
End With


Set rng = Nothing
On Error Resume Next
Set rng = Selection.SpecialCells(xlCellTypeVisible)
On Error GoTo 0

If rng Is Nothing Then
MsgBox "The selection is not a range or the sheet is protected" & _
vbNewLine & "please correct and try again.", vbOKOnly
Exit Sub
End If

With Application
.EnableEvents = False
.ScreenUpdating = False

For Each sCell In R

att = Range("C4").Value
If Dir(att) = "" Then
GoTo Last:
Else


With iMsg
Set .Configuration = iConf
.to = ""
.CC = ""
.Subject = ""
.AddAttachment (att)
.HTMLBody = RangetoHTML(rng)
.Send
End With
End If

Last:

Next sCell

With Application
