   parties, and for those other parties to advertise their willingness
   to receive such feedback.

While the first bullet restricts reported messages to those
originating from the networks of a report's recipients, the only hint
toward such interpretation in the second bullet lays in the term
"outbound".

Section 2 of draft-ietf-marf-reporting-discovery repeats the same
phrases, and explains how reporting discovery is going to support that
purpose.  In case the wording in MARF-BASE is misleading, the new I-D
should clarify it.

For a nit, the I-D "addresses *three* primary use cases", but then
only two of them are bulleted.

For a core issue, it is a fact that some abuse teams only want reports
that concern mail originating from theirs.  Thus, we should ask
ourselves how prominent the origin of the reported message has to be
in reporting discovery.  Is it more important than *feedback type*?

Suggesting that the discovery mechanism should have fine enough
granularity to allow a consumer to indicate which types of abuse
reports they want to receive in ARF format.

I could help with the DKIM, ADSP, and/or ARF portions; I don't know SPF =
well enough.

As for whether the split is necessary...it'd certainly be easier for =
someone who is only implementing DKIM, or only implementing SPF (it's =

implementing DKIM or SPF or both.)  But it could be frustrating if =
someone is implementing them all at once.  So, I'm not sure which way to =
go.

I'm definitely in favor of splitting out the redaction discussion to a =
new Informational or BCP document, because I expect that other MARF docs =
will reference it often.

Hmm.  I could imagine a scenario where someone with hundreds of domains =
uses the include mechanism to ensure that all of the domains have the =
same SPF record, and they'd want reporting to work.  Since SPF isn't in =
a service record like _spf.example.net, CNAMEs generally aren't an =
option.

Maybe all we can do is suggest that includes only be followed a few =
levels (or is this already in SPF?)

I think it should be in its own draft.  ARF probably won't be the only =
format where a discussion of redaction is appropriate.

This also gets into the overlap between dkim-reporting and =
reporting-discovery, which we should probably discuss further.

There's no reason the advertisements described in reporting-discovery =
couldn't be used for auth-failure reports -- except that the mechanism =
for looking up the advertisement in reporting-discovery may use a =
different identifier:

R-D Report Consumers advertise at:
	destination of PTR of outbound SMTP server
	DKIM d=3D

R-D Report Generators advertise at:
	recipient domain (RCPT TO: <foobar@example.com> =3D use =
example.com)

D-R Report Consumers
	DKIM d=3D
	SPF MAIL or HELO

Sometimes they'll match, sometimes they won't.

Also, it does make sense to tie reporting of authentication to the =
authentication-related DNS records rather than creating a new record.

The identifiers used in reporting-discovery to identify feedback =
consumers may be too limited to make dropbox reporting easier than it is =
currently.  A message referring to a dropbox at yahoo.com won't (in most =
cases) be signed by yahoo.com, so you can't be certain of finding the =
appropriate advertisement via the DKIM d=3D domain.  It also won't (in =
most cases) have been sent by an MTA within the Yahoo! ADMD, so you =
can't find it via the PTR record of the border MTA.

It's /possible/ that the dropbox address's DNS domain (RHS) will be the =
same as that DNS domain's d=3D value, but that's not certain.

Dropboxes and other identifiers found solely within the message may be =
out of scope for reporting-discovery, unless we can think up a way to =
make it work.

[as participant]

I think my preference given the input so far is to leave (1), (2) and (4) i=
n one document since there's already one such implementation out there (gra=
nted it's mine; I admit to some bias there).  (3) could go out on its own a=
s an add-on to that one, and Scott has volunteered to edit that; (5) could =
also go out on its own, probably as an informational or an update to RFC596=
5, and I think JD is saying he could take that one.

How does that sound, especially to those I've actually named here?  :-)

Makes sense to me, assuming there's consensus to split.  I'm willing to =
become editor of (5).

If all the work is going to be done at the same time, I don't see any
benefit to splitting out the SPF stuff.  It may be a political issue
to refer to an experimental RFC, but unless the IESG insists, our
readers will prefer to read one document.

As far as (5) is concerned, I'm one of the authors of 5965 so I'd be
happy to work on it with JD.  This seems somewhat independent of the
rest since it's equally useful (or not) in existing ARF applications.

R's,
John

Currently a record can say

   _report.example.com. IN TXT  ( "r=abuse@example.com; rf=ARF; "
       "rt=abuse,fraud,virus; re=postmaster@example.net;" )

We could add a tag, say, ro= (o for *origin* of the reported message),
and possibly go= for generators.  The values would indicate classes of
reported messages that are relevant for reporting.  For example,
classes could be defined like so:

  *a* reported message is *authenticated* by DKIM, SPF, or other
      mechanism that proves it originated from the relevant ADMD.
  *b* reported message is *believed* to originate within the relevant
      ADMD, as determined by inspecting Received header fields, rDNS,
      block assignments, and similar ways.
  *c* reported message is *crap* with the Return-Path and/or From
      header fields abusively referencing the relevant ADMD.
      (Hey, this is just an example!)
  *d* reported message has a *dropbox* in its text, or in the From or
      Reply-To header fields, referencing a seemingly existing
      address in the relevant ADMD.

For report consumers, the relevant ADMD is the target domain.  Thus, by

   _report.example.com. IN TXT  ( "r=abuse@example.com; rf=ARF; "
       "ro=ad; re=postmaster@example.net;" )

example.com would state that they are interested in records about
messages that authentically originated from theirs, or that deploy
dropboxes related to them.

Note that the latter example omits rt=.  We could argue that frauds
are probably related with dropboxes, or that reporting abuse is only
interesting for messages originating from the relevant ADMD.
However, imposing more semantics on the feedback-type doesn't seem to
be viable.  Hence we add a new classification that is suitable for
reporting discovery.  Would we still need feedback-type, then?  If
not, then the new classification would also solve the problem of
adding other rf=, like IODEF, whose types are different from those of ARF.

Hi all,

One of our chartered items, and one that's very much past due, is a "best p=
ractices" document about feedback loops.

JD has submitted a draft that is an I-D version of the MAAWG BCP document (=
draft-jdfalk-maawg-cfblbcp).  The MAAWG board would like to retain change c=
ontrol for now and thus is seeking to progress the document along the Indep=
endent Submission path.  However, they are also aware that a faster path to=
 publication would be collaboration with MARF.

I would like this group to review the draft and determine how much we agree=
 with it and would like to have it as an IETF BCP product of MARF.  If ther=
e are major topics that are absent or with which we disagree, we need to bu=
ild that list.  Once that's done, we can negotiate with MAAWG whether or no=
t we want to incorporate our proposed changes into their version, or use th=
eir document as a basis for our own (with, of course, appropriate attributi=
ons).

Please review the draft and submit comments.  Ideally this would be a discu=
ssion item in Prague.

Thanks,
-MSK
