Hello colleagues

We are implementing a new policy in our agency and my boss is asking me if there is a way to prevent users from achieving email attachments. He would like to see if there is a way to configure GroupWise on the domain or post office level to only allow the users to archive the emails without the attachments.
GroupWise 8 sp3 running on NetWare 6.5 sp8 (still)
As always, thank you for being there,
