Another suggestion was that SMTP headers always contain the
IP address. I've seen this in quite a few mailers already.
All we need is a slight modification to the SMTP Receipt
standard. This could be a Best Current Practice, quickly
Hm, this is already covered. RFC 1123 says:
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.
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).
