Folks,

As far as I know, the INTELPOST electronic mail system was the first to
adopt TCP/IP circa 1982. This is a facsimile-mail system first built by
BBN and then rebuilt by COMSAT Laboratories. It was operated by the US
Post Office and overseas affiliates. It use PDP11/40s and the fuzzball
network code. I know not if it is still in business.
