[dmarc-ietf] hints for receivers

[Tim Draegen <[e-mail]>]

I like the spirit J. Gomez's "l={yes,no,dunno}" proposal, but have been struggling 'cause I don't think it would be effective in the wild.

While grinding up a batch of coffee beans, it struck me that "l={yes,no,dunno}" is part of a larger category of "hints for receivers".  As such, would receivers make use of high-level sender-provided descriptors of email category?

For example, "l={yes,no,dunno}" could be realized with a "category={transactional,newsletter,organization/corporate}" type of tag.  In this way, receivers would use the hint "category=transactional", see that the message came over a mailing list (transactional email shouldn't come through a mailing list, right?), and act appropriately.

PS.  The "l={yes,no,dunno}" tag attempts to prescribe whether or not a domain is excepted to arrive through a "list".  From the receiver PoV, is a description of the content of the email more generally useful?
