Nice idea, but there's no way to distinguish between people and
programs connected to a port. You could do some heuristics based on
the delays between responses, assuming that humans are slower and/or
less consistent, but that's not foolproof. Echo isn't handled by the
smtp server, it's done by the telnet client, so there's no way to
disable it from the server side.
