Re: [dmarc-ietf] SPF doesn't accommodate third level .name domains?

2022-06-01 Thread Phillip Hallam-Baker
It looks like VeriSign has hit on the same solution to the personal PKI
problem that I have in the callsign registry and for the same reason: To
get around the problem that a certificate for al...@example.com doesn't
work to authenticate Alice unless she is the holder of example.com.

Building out the registry co-extensive with the PKI removes the need to
validate the certificate requests for holdership of the domain because this
is established by definition.

It also looks like they have hit the inevitable constraints from trying to
engage with the legacy SMTP installed base to make it do something
different. And I can't see that problem as having a good solution. SPF was
not designed to support the case where al...@example.com was in a different
domain of control to b...@example.com. The .name use case is not going to
have nearly enough of a user base to cause deployment of a proposed change
to SPF to solve the problem.

The only approach I can see working is for .name to provide the inbound and
outbound mail services. Which given how SMTP works for inbound they must
surely do anyway.

Accusing other people of disagreeing with you because they fail to
understand your position and that they would agree with you if only they
did their research is a rather aggressive move.

It is the constant refrain of the coinsplainer community.

If your goal is to preserve the status quo without actually defending your
position, telling people that it is incumbent on them to find the arguments
against their proposal and agree with them does the trick.


We do need a better way to track architectural arguments so that they do
not get lost. There is another form of this particular pathology which hit
us with the DNS CAA record which I proposed before the DigiNotar attack,
became an RFC but nobody took any notice and then a few years later, a new
issue came up and we ended up with a CABForum mandate to deploy.

I never considered CAA perfect, it was a compromise between a set of rather
ugly constraints imposed by DNS DNS-ing. By the time we got round to the
BIS, I had forgotten the rationale for the compromises. So we changed them.
And then spent three years in a set of stepwise refinements that brought us
back to the starting point because DNS is still DNS-ing and even harder.

Re: [dmarc-ietf] IETF Process/Culture was Re: 3.2.6 The meaning of non-existence

2021-12-18 Thread Phillip Hallam-Baker
My analysis is rather different but comes to a stronger statement of John's
point.

Mailing lists are not well supported by SMTP and never will be. Any
discussion of how to make mailing lists work better has to begin with the
acceptance that they will never work very well which is what most people
have been arguing in this thread.

That does not mean that we should not attempt to make changes but it does
mean that any changes should be considered through two lenses, not just
one. First 'will this make mailing lists a bit more tolerable', Second,
'will this help a successor technology work better'.


Rather than seeing mailing lists as they work today as the pinnacle of
evolution, we should see them for what they are, a rather disgusting hack
that we never got round to fixing.

Why is it assumed that the input to a mailing list is an SMTP email? That
seems to me to be a rather narrow assumption.

I am typing this into Gmail, why assume that my HTTP transaction must be
mediated by an SMTP transaction to reach a mailing list user? Why should
'mailing list' necessarily involve SMTP at all?

Once we recognize that the inputs and outputs from 'mailing lists' can be
through other transports than SMTP, all arguments about preserving
'original' headers collapse. This is not an interaction between an SMTP
sender and receiver, the mailing list itself is a principal.


I am of course aware that you can read IETF lists via IMAP, NNTP etc. In
the short term, those efforts are being hobbled by the lack of decent
clients. If the Web 4.0 folk get somewhere with a new generation of user
centric social media, that might change.

2021-12-18 Thread Phillip Hallam-Baker
Anyone raising 'Chesterton's Fence' sets my teeth on edge.

There is a longstanding field of political engagement called Agenda Denial
that deals with winning arguments they cannot possibly win by making sure
the argument is never made.

It is never the right time, and never will be.

There will always be something that must be done first.

The people raising the issue have raised it in the wrong way.

The issue needs more study.

G. K. Chesterton was a rather unpleasant chap. Like most of the English
establishment of the time, his goal was to avoid sharing any of the wealth
of Empire with the undeserving masses who created/looted it.

I strongly caution against anyone attempting to raise his standard in a
technical discussion.

Only because we haven't got email security properly sorted.

I can't remember the last time I received a real letter. All I get is junk
mail and bills. And the bills arrive because we haven't got the standards
for doing it electronically established yet.

Within a decade postal mail and the telephone will have become as
functionally obsolete as fax. It will take a lot longer for them to
disappear, the telegram only stopped last year, about a hundred years after
it was utterly obsolete.

The postal service will continue of course until Bezos works out how to get
his drones to work.


Technology does change over time. There is a very clear demand for an open
Dropbox like solution. There is a clear need for a protocol that allows
email like subscriptions to blog comments without the mailbox clog that
results.

Absent specific government action to protect the tenant, the landlord can
abuse them in almost any way they choose. Which is why we have voluminous
legislative protections for tenants. There is an entire field of law
concerning that.

The reason that is necessary is that the alternative to renting is very
expensive and requires a large amount of capital. But if houses were $6
then it would be perfectly reasonable for society to tell tenants that they
are on their own because they should become freeholders.

My point is that mail is an old protocol and people who expect that it can
be kept going unaltered in its original form serving all the purposes that
it was never designed for but have emerged over time are going to be upset
no matter what.

Spam is an attack. The people who send spam are hardened criminals who have
murdered at least two people in the past five years. It is futile to expect
that the mail system can continue to operate without changes.

The major ISPs can and will and SHOULD consider the interests of the
majority of their customers as they move forward. If they don't, open email
systems based on SMTP will go the same way as USENET and die because people
don't want to put up with them any more.


The possibility that SAP might force you to subscribe to IETF lists through
a different address does not worry me in the slightest. That is not one of
the uses of email that I consider any sort of priority. I am quite happy
making you change your mail config.

But looking further ahead, it is becoming clear that maintaining mailing
list capabilities is going to become increasingly difficult in the face of
escalating anti-spam controls. Which is why I suggest that rather than the
IETF community reacting to DMARC by refusing to consider any change that
inconveniences members of its club, IETF instead designs a protocol that
addresses the actual needs.


In the SMTP/IMAP model the message is pushed to the sender outbound MTA,
pushed to the receiver outbound MTA and pulled by the client from the
outbound MTA.

The SMTP/IMAP model is thus PUSH/PUSH/PULL

The model of NNTP and Dropbox and many of the blogging comments apps is
PUSH/PULL/PULL. That is a message pattern that we can and should support in
IETF protocols. Because when someone is sending 10Gb of data, the PUSH/PUSH
model is not viable. Better to leave that data siting on the outbound
server rather than have it clog up hundreds of inbound servers and sit
unread.


US6192407 has a priority date of Oct 24, 1996, now would be a good time to
work on such a protocol.

No it is you who don't see the parallel. Google and Yahoo's position
here is analogous to that of the MBTA, they are one entity with a lot
of money but they are acting for the benefit of thousands.

Meanwhile we have a bunch of privileged Internet early adopters who
think that the rest of the world should revolve around them.

The number of people using Yahoo/Google is over a billion. The number
of people being inconvenienced by DMARC more than they spend effort on
complaining about it is likely to be zero.

The issue here is not that the yacht owner is rich, it is that there
is one person able to inconvenience thousands by citing a precedent.

Yes, its not just SMTP that is going to be extended with as policy
layer. Every Internet protocol will be covered by one.


Back in the day I was the only person saying that NAT was the
deployment mechanism for IPv6, not something to be deliberately
sabotaged because it does not meet some IETF dogma.

I was right then and I am right on this one. DMARC is the right way to
do email. It is over done, deployed. The only question that is left
for the IETF now is whether to fix any damage it might have caused and
if so, how.

When was the last time I was wrong on something like this? It is

You don't understand the Internet then.

All that makes the Internet different is that everyone has that same
exit option. The only sine qua non of the Internet is that networks
communicated via IP. That is a strict rule but it is the only rule.
Everything else is on the table and anyone who wants to do something
different can.

And there is nobody to go to to ask permission.

The Internet is an empowerment technology. Or at least it is since the
Web reworked it. The goal of the Web was to put publication
capabilities in the hands of everyone so it wouldn't just be Rupert
Murdoch who could decide what was news.

We don't have rules, we have conventions and standards. But anyone who
does not like those standards is always free to rip them up and do
something else. This is not a decision making body.

Yes, always best to act before thinking about the problem

Always best to make sure that the group considers only the problem it
is allowed to consider.

How can the IETF be a consensus organization if people are allowed to
block consideration of alternatives?


My understanding of the remit of this group is to consider what to do
about the DMARC situation.

The reason I proposed looking at changing the mailing list scheme is
that the DMARC 'discussion' consists of one group of folk saying 'we
have to stop this' and another pointing out that it has already
happened.

Most Internet users do not care whether mailing lists work or not. So
expecting them to accept tons of spam from criminals trying to cheat
them to preserve the equivalent of vinyl records is not going to
succeed. The Internet does not have a rule that the people who got
here first make the rules. There is a traffic jam in Cambridge/Boston
several times a day as the lifting bridge opens to let some plutocrat
sail his yacht through at rush hour. Several thousand people have to
wait half an hour to get to work for one person to enjoy their hobby.
I think that is a rotten and selfish way to run things.

So given the fact that DMARC is causing problems for mailing lists we
should not automatically assume that the solution is to change DMARC.

I think that this point is completely on topic for a pre-WG list that
is discussing ways to address a problem. Chances are that the
conclusion is going to be that NO DMARC WG is formed because the
people using DMARC are not interested in the changes that are going to
be proposed.


Mailing lists are not an optimal solution. They have high
administrative burdens, the mail they send is often caught in spam
filters because a mailing list is a bulk sender. These problems were
recognized when NNTP was designed. Though as Dave Crocker points out,
flood filling is hardly an approach we should endorse for the modern
Internet.

But given that we have the attention of Google and Yahoo here we do
have the critical mass that could make a major change in mailing list
technology stick. And it is to their interest to do so.


So I am not just proposing a better solution, I am proposing a
solution that has more chance of being adopted. Though since 'shut
DMARC down because we says to' is not going happen pretty much
anything has a better chance of deployment.

NNTP was designed 30 years ago. We should consider moving on. The
modern protocol world is JSON/REST

Well you don't get the difference between the Web and the Internet then.

We built the web on a model where the individual was empowered. Having
to get a proposal for a newsgroup approved by an amorphous collective
isn't empowering. The lack of clear control does not mean that there
isn't any. It just means that the control is exercised without
accountability.

NNTP was built to save bandwidth, hence the need to manage what data
went where. But we could certainly drop the server-server copy
functions and just declare the mailing lists as site local.

The problem with that approach is that we then have to have accounts
and the single log in problem grows unless we interface to one of the
single log in schemes, all of which have problems.

Any subsequent problems are irrelevant unless FedEx, the owner of
fedex.com considers them to be relevant.

That is what folk complaining don't get: you don't have the right to
use your employers email or a public email provider's email any way
you want. The domain name owner makes the rules.

As Craster insists: My domain, my rules.


If you want to make the rules then get your own domain. I think that
is something most IETF participants know how to do.

In the medium term, lets kill the stupidity of mailing lists with a
protocol that works. NNTP was originally designed to replace mailing
lists. It actually works quite well at that. The only problem was the
IT-Dictator mindset that underlies it: newsgroups have to be approved
by the Commune!

The idea that newsgroups work by the mail client PULLING a list of
unread messages and then PULLING those that are to be read is the best
architecture for newsgroups.


I am currently using 8Gb of my primary Gmail account space, 80% of
that is my mailing list mail. Google and Yahoo could both save tens of
millions of dollars worth of hard drives a year with a better
protocol, thats incentive to invest.

The only points that need to change are the mailing list programs need
to offer a very simple network API and the clients need to accept it.
The second is not so difficult to deploy for the 90% of webmail users.
