Email History through RFCs

Many aspects of email are a lot older than you may think. There were quite a few people in the early 1970s working out how to provide useful services using ARPANET, the network that evolved over the next 10 or 15 years into the modern Internet. They used Requests for Comment (RFCs) to document protocol and […]

The Physics of the Email Universe
