Grr. Doesn't describe the problem! Is it that a QuickBooks client using a mailbox at a "p=reject" domain is having QuickBooks send invoices on their behalf? If that's it, I have a great deal for them. Register a domain and get their company name, instead of Yahoo!'s, in From:. Or (cheaper), Quickbooks just checks for "p=<not none>", and if so overrides any company-specific config, and puts QuickBooks in From: (with a working "p=reject" policy, even!), "Your <month> invoice from <company>" in subject, and the company address in Reply-To. Even supposing the company doesn't like either of those options, it's not clear to me that the "p=reject" domain is going to necessarily be happy trusting QuickBooks, even once TPA-Labels gets implemented. > I know of many small operations with similar services and > previously working strategies. Much less so the effort required to vette a million small operations (who could actually be the Yahoo! customer requesting a TPA-label for a vendor they use -- how does TPA-label deal with collusion between authors and relays?) So, yeah, I sympathize with the Mom & Pop shops whose kids go hungry this month because the bills didn't go out, and with the small operations tearing their hair out because they've got a thousand paying customers at Yahoo! whose content isn't arriving at destination, but I really don't see TPA-Labels as a solution to this problem yet. > > Again, I seem to require an additional clue.

We already have such a channel (the _dmarc subdomain). What is this new channel for? _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
