Given that the 5322.from is crucial for DMARC, and the 5322.from
is transmitted after DATA, how can you evaluate DMARC before DATA?
You can't evaluate DMARC before DATA.
Sure you can. I explained how it can be explored today!
Right now, today, it can explored with an existing protocol just was
recently made historic:
https://tools.ietf.org/html/rfc4405
The status change was done because this protocol was part of the
SenderID vs SPF experiment and SenderID lost. SPF was made a standard
track protocol. It does not mean we could not consider leveraging
the exist SUBMITTER code for other purposes and its a right fit for a
high overhead payload technology in DMARC. I will suggest it can offer
a high optimization payoff:
- Eliminate payload reception overhead, yet still
- Provide DMARC reporting and disposition override capabilities.
I don't think its an "Horrible Idea." I think its a great idea. :)
