John -
Can you tell me what if anything has been decided
concerning writing either marid protocol or marid core so
that in addition to checking for a malformed SMTP mail
from, an SMTP mail from check is a suggested
pre-cursor to 'swallowing' the message and doing a PRA
check?
The current MARID scheme, as described in the marid-core and
marid-protocol drafts, doesn't discuss a SMTP mail from at all. MARID
as a working group has been moving forward on a scheme that checks the
PRA, and adds the SUBMITTER extension as a way to do that check before
"swallowing the message".
Currently, the drafts are:
draft-ietf-marid-core, which describes the basic system and the PRA
algorithm
draft-ietf-marid-protocol, which describes the record format and the
mechanics of checking it
draft-ietf-marid-submitter, which describes the SMTP extension
At IETF 60, it was agreed that the PRA algorithm should be split out of
marid-core into its own draft. This is not because there are other
identities being checked by the current MARID scheme, but because there
was a request that the PRA algorithm in and of itself was useful in
other situations, and it would be easier to reference if it were in its
own draft. This does leave the core document with just the overview,
and the interface logic to SMTP and MTAs.
That said, working group last call on these documents (actually, the
new versions being prepared this week) is scheduled for August 23rd.
In the following two weeks, the working group will discuss and debate
PRA for MARID, and either pass it or reject it forever. It should be
noted that if it is rejected, the protocol draft is written in such a
way that it can be passed and advanced, even as the group decides on
which identity to use instead of PRA.
Lastly, since others seem to have been confused in the past: I AM NOT A
WORKING GROUP CHAIR. I speak from my understanding of what is going on
in the working group, not from authority to make it happen.
