The reduced process limits has existed dating back to Feb 23, 2004 in the libspf-alt implementation. It was picked up later (still pre-MARID) by at least one other SPF implementation. > There was a change that including HELO in > parallel with the MAIL FROM rather than when the MAIL FROM was NULL. Independent HELO checking was argued for since the summer of 2003. The Spamassassin development version was doing HELO checking in the Dec 2003 or Jan 2004, I'm not sure which. The change in the spec dates back to May 16 2004. While MARID was going on at that point, it was still before the MARID WG had adopted any drafts. In reality, this is an incredibly minor change because almost all MTAs send email with a null MAIL FROM every once and a while, so the HELO domain would be checked at least some of the time. Having it be checked all the time makes very little practical difference. > A number of other changes have since been struck. Yes, there were a HUGE number of incompatible changes made during the MARID process and, in hind sight, starting with the MARID drafts and trying to make it compatible was probably a mistake. However, we did try to eliminate as many changes as we could find. > Problems created > when modifying record processing or what identifies are applied could > be ameliorated through use of record versioning. Maybe, but the implementations that did the processing limits were deployed in early 2004, so unless you have a time machine, we are pretty much stuck with them now. > While I agree with the view that PRA semantics may create problems s/may/will/ > when applied against the initial record version, the Sender-ID draft > permits the use of a scoped version of the record which makes it > clear what semantics are expected. Our goal in writing the spf-classic draft was to document what is and was, not to create something new. The job of creating something new was given by Ted Hardie to the MARID authors. > Accommodating this identical > provision within SPF would have resolved the potential Sender-ID > conflict and also would have been a means to acknowledge adherence to > newer processing limits and HELO checking, for example. The SenderID drafts have never contained the HELO identity. This makes it not fully backwards compatible with SPF-classic. The SenderID drafts are not under our control, so we can't fix it. -wayne _______________________________________________ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf
