Thanks for clearing that up.

Yup, back in the early days of big corporate networks you didn’t even necessarily qualify for access to the internet “gateway”. We used to use a messaging system called Lotus cc:Mail, which allowed you to address messages within the business anywhere in the world using an addressing format that looked a bit like this:
To: John Smith AT CORPORATE
But to send email outside the business it would be
johnsmithswife@ntlworld.com AT INTERNET
Needless to say you were only allowed access to the internet gateway if you had a valid business reason. As businesses moved to mail systems like MS Outlook or others that seamlessly integrated intranet and internet messaging, they tended to adopt today’s more familiar email addressing format, so today John’s messaging address regardless of whether he’s being contacted internally or externally is
John.smith@globalbogroll.com . But there is still a corporate network hiding behind it all, which transfers email within the busniess, without tasking the public internet service.
