Yep. If you're going to hold me to "The recipient decides," then
hold me to it here, too. As I've noted, I don't want a third-party to
implicitly tell me to treat all senders as suspect until proven otherwise.

Good question. My idea of demonstrating accountability, at least per
domain, is the domain identifying a sending host as one of theirs. All of
the proposals to date use this approach to let a domain administration
demonstrate accountability. There may be better ways, which is what I
believe we're here to find.

That's not very accountable, agreed.
I want to be able to complain to a domain in the following escalating
order (this is just my preference): abuse mailbox (if it exists - it's not
required), postmaster mailbox, whois contacts, hosting ISP. From there I
want to refuse mail from the domain if it's unresolved.
I can't do that if the mail claiming to be from a domain isn't really
from the domain, or isn't from a user or host the domain's accountable for.

I'd like to think THAT's one of the reasons we're here. To provide a
way for an enterprise to demonstrate e-mail accountability.

The receiver decides, and I would never fault you for wanting this
kind of information before accepting a domain's mail. I'm not comfortable
with it and I believe it has too-high a barrier to entry for senders. If the
domain administration can tell me directly I'll trust that first. Finding a
way for them to tell me, again, is why I believe we're here.
