Re: Last Call: Change the status of ADSP (RFC 5617) to Historic

I agree, the problem IMV is the illusion that DMARC will replace it has some domains has already done by switching their strong exclusive mail operations declaration from _ADSP TXT record policy to a _DMARC policy. Like FACEBOOK.COM. The REJECTING/DISCARD concept is still the same and active, just a different TXT domain policy protocol describing the expected behavior.

The problem I have is the lack of confidence that DMARC will be supported by the main conflictive software in the entire DKIM deployment and service architectural picture -- the resigners (mailing list software). Thats the problem ADSP had. DMARC does not change it.

So is making ADSP historic, killing the investment done with DKIM/ADSP support, going to be replacing with a plug and play protocol switch with DMARC?

If so, I don't like that lost of investment but I can support the move but now, not as an early adopter and I will wait until other mailing list software vendors/developers add that necessary support for DMARC rejection policies. Its the same proof of concept issue as it was with ADSP.

DMARC just add some reporting, logging and feedback concepts to the picture.

ADSP was basically an experiment that failed.  It has no

solve is now being addressed in other ways.

I oppose to the change as proposed, and support the
explanation called for by John Klensin instead.  Two arguments:

1)  The harm Barry exemplifies in the request
--incompatibility with     mailing list posting-- is going to
be a feature of at least one     of the other ways addressing
that problem.  Indeed, "those who     don't know history are
destined to repeat it", and the explanation     is needed to
make history known.

2)  A possible fix for ADSP is explained by John Levine
himself:
http://www.mail-archive.com/ietf-dkim@xxxxxxxxxxxx/msg16969.ht
ml     I'm not proposing to mention it along with the
explanation, but     fixing is not the same as moving to
historic.  It seems that it     is just a part of RFC 5617,
DNS records, that we want to move.

Ale,

Just to be clear about what I proposed because I'm not sure that
you actually agree:  If the situation is as described in the
write-up (and/or as described by John Levine, Murray, and some
other documents), then I'm in favor of deprecating ADSP.  The
_only_ issue I'm raising in this case is that I believe that
deprecating a feature or protocol element by moving things to
Historic by IESG action and a note in the tracker is appropriate
only for things that have been completely ignored after an
extended period or that have long ago passed out of public
consciousness.   When something has been implemented and
deployed sufficiently that the reason for deprecating it
includes assertions that it has not worked out in practice, I
believe that should be documented in an RFC both to make the
historical record clear and to help persuade anyone who is still
trying to use it to cease doing so.

There may well be arguments for not deprecating the feature, for
improving it in various ways, or for contexts in which its use
would be appropriate, but someone else will have to make them or
propose other remedies.  I have not done so nor am I likely to
do so.

   best,
     john
