Okay cool, I believe I have successfully installed the one from this thread thanks to your help, NTLDR, we will see if I run into any problems or if its what the client wanted exactly...they are German so I still need to change and translate a few items.
I did a quick test sending to the admins only and it seemed to work fine for me.
If it doesnt work well I will upgrade or change over to the other version you supplied, hopefully there isnt too much to change...
Cheers...and thanks for all the help.
