It would appear that if you create a Data Control Policy which prevent users from emailing file types to unauthorised email destinations like gmail, webmail, hotmail and attach any document from a network directory it allows the email to be sent (Shocking).
If you attach a file from your local machine it blocks the file fine, it would seem that the Sophos agent has difficulties understanding mapped drives which it pretty shocking for a security product.
Note:
I have sent this information to Sophos to review and I may have missed something so don't take this as gospel. This maybe an isolated issue which is happening in my environment.
