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.
