Or was that just a belch in mid-sentence :-)? Reverse Address Resoloution Protocol. When someone connects to me, I can always geet the IP address they are connecting from. Using RARP, I can turn the address into a machine name, and compare it with what you tell me on the "HELO" and "MAIL FROM:" lines. RARP does hardware address/IP address translation. Redirected to chat.
