From: Havard.Eidnes () runit sintef no
      5.2.8  DATA Command: RFC-821 Section 4.1.1
...
         *    The FROM field SHOULD contain both (1) the name of the
              source host as presented in the HELO command and (2) a
              domain literal containing the IP address of the source,
              determined from the TCP connection.
...
         DISCUSSION:
              Including both the source host and the IP source address
              in the Received: line may provide enough information for
              tracking illicit mail sources and eliminate a need to
              explicitly verify the HELO parameter.

Thus, this is not a new suggestion (RFC 1123 is dated Oct 1989).

You are correct.  Good memory!  So, how do we enforce a 6 year old RFC?
