I have been playing around this afternoon with the data control policy. Managed to get a rule configured to block all file types apart from .7z to prevent the transfer of data via email and removable storage.
Sophos is blocking the transfer of data onto a usb stick unless it's in a 7zip format which is good. But it's not blocking any email attachments that I am adding to the Office 2007 Outlook client. I can send any format out and Sophos doesn't prevent this.
Anyone have any ideas on how to fix this?
