... And I don't see the point. You can only fool users of your own
server, whether they be local or of some other address class. Surely
they know (and NEED to know) the IP address and name of your server?
When your server sends mail to mine, mine will add its own Received:
header, containing your server's IP and reverse DNS. You cannot hide
that, unless you're using compromised machines (spam zombies) or open
relays. And in the latter case the relay is likely to add its own
Received: header with your server's IP and rDNS.

mail to this address is discarded unless "/dev/rob0"
