How do I make the SMTP Greetings Banner to display the remote client's

what do you gain with that?

* the ordinary user never will see it
* the tech user with telnet knows how to get that infos
* the spammer don't bother about "Please, do not spam"

it's not more worth than disclaimers in email signatures

I guess you are completely right.

Not completely.

It is a fairly common problem for senders to unknowingly pass mail through transparent(ish) proxies that may talk to the receiving MTA with a different IP than any directly used by the client machine. It is useful for a server to expose how it sees the client because it can aid independent problem analysis by senders with problems.
