Ok the user's emails should not go through any other servers out on the internet to reach mine. Meaning their emails are sent directly within the server. so if j...@restricted.com sends to j...@restricted.com, nobody else should be able to read that email, no ISP, or any system. I understand how normal emails work. from yahoo to gmail. the yahoo servers hop through to get to gmail. since my server is only 1 box and the users are local users, (only one domain in the virtual domains table), then is this email sent within the server or does it hop from the client's internet connection to get to my server?
