Yep, but that was not smtp, which is what I thought we were talking about. Smtp came about to connect servers, so that users could send email to those on other systems.
smtp was intended to connect machines (servers or not). And the machines would have several (many?) users, using the program "mail" on unix or something similar. The users could mail one another inside the same machine, or users of another machine. Then came machines that were not reachable by name on the internet, or not permanently connected. These used smtp to send email to another machine that was, and acted as a mail server. Initially, those mail servers were working as open relays, abuse had not started. -- Cheers / Saludos, Carlos E.
