I don't know what jefsey means by "IP zones" Louis and I met in 1973 and his datagram ideas, sliding window ideas for flow control, influenced my thinking about TCP. Gerard LeLann, who worked in Louis Pouzin's group at IRIA came to Stanford in 1974 to work on the TCP and Internet. IEN 48 refers to "catenet" - a term invented by Louis. So Louis deserves recognition especially for his work on datagram networks. I can't speak to the email matter, not having any personal knowledge beyond the work of Ray Tomlinson at BBN in 1971 and Douglas Englebart at SRI in the mid/late 1960s.

He specified the first "mail" program at MIT, the scripts, the end to end datagram, the IP zones (recently Vint recalled the Internet could have been called "catenet" from his multiple routes concatenation approach - I think is the necessary future).
