Many different people within an organisation create invoices, purchase orders etc & any queries should be replied to the salesman / buyer !

Even though the body may contain the following ...

If you want to query or confirm the order then please notify the buyer -  ${PURCHASEORDER.CF.Buyer}@£$%£$%$%^$.com

The recipient normally chooses the "reply" button (ignores the above) & has to be forwarded every time :-(
