There's a strong reason for this: the immediate client IP is the one fact about *every* MX-driven attempt at message transport that the receiving MTA can know with very high certainty, even when the message is originated by someone who intentionally and maliciously tries to hide his identity. Whether accountability *should* be tied to that one knowable fact is a philosophical question. As a practical matter, there has proven to be little choice. For some years early in the growth of spam, filtering techniques were applied and over time largely discarded or relegated to scoring systems which assumed that spammers would not falsify other elements of mail and its transport that should lead back to the ultimate originator or to someone who can identify and police the originator. Having run out of headers and transport features to check, we've developed new things like SPF and DKIM that are harder to spoof but suffer from inadequate adoption to really fix a large part of the problem, much as the previous transport and content encryption and signing mechanisms have.
