Sage 500

Does anyone have step by step instructions on how to set up emailing invoices on version 7.40.20? I was told that I had to use the primary contacts email address. I would prefer to use a secondary email address.

The Release Notes document for the Sage500 ERP January 2015 are not located with the downloads for the client, server and source as they typically are. Have these been posted yet? If so what location/link can these be downloaded from?
