Doug,

In lieu of no MUA that currently supports your DKIM address book ideas, are you suggesting that every SMTP or MUA system that is waiting for the standardization of DKIM will also have to use Levine's and Hoffman's new non-standard, untested, unverified, no threat analysis, commercial DAC venture in order to get any PAYOFF or BENEFIT from DKIM?

In other words, are you saying without DAC, DKIM is useless?

DAC provides guidelines for creating these lists, if I am not mistaken. So not even DAC offers a full-up solution, just as DKIM does not either. There are some start-ups already offering plugins for the popular web and email-clients based upon their own lists. I can obtain that today, and months prior.

Is this the reason why SSP is being brushed aside? Because the DAC group have succeeded in clouding the SSP picture and non facts that it work hence the non-standard DAC should be used instead with DKIM?

I suspect that all methods that enable recipients the ability to protect themselves will be tried. A restrictive SSP however will create the greatest trouble for the least benefit. There are areas of weakness that can be repaired using associative techniques, from protecting a white-list to protecting the MailFrom.

The why are we wasting time with SSP requirements. If enough people here are so CONVINCE that DAC is the ultimate technology to be used with DKIM, why they do do an official IETF I-D proposal? Why did Paul Hoffman, one of the Key IETF GODS, stray away from using the IETF to standardized DAC?

Even waving a magic wand will not overcome several issues that need to be resolved such as protecting white-listing, the MailFrom, and allowing sign-domains to be used for annotation without the sharing of private-keys. All of this becomes possible with the right type of policy where recipients are better protected, email delivery is not negatively affected, and there is greater freedom of choice regarding how a domain is associated with their provider.

I'm sorry, you have to excuse me, but I am engineer at heart, and none of this make sense to me. Too much politics and self-interest for me going on here.

This is not about politics or self-interest, other than also being someone that uses email. DKIM will make life better, but associative schemes will not shift benefits to one group or the other, just away from the bad-actors.
