Yahoo! will interpret a p=reject policy as meaning that we may at our option reject any mail that fails DMARC.
We will NOT promise to correctly identify mailing lists and save your mail; nor will we promise to reject all the mail.
I note that we enjoy rejecting mail, but not at the expense of making users very sad. We do, in fact, use DMARC to
Once again, I strongly recommend using p=reject only for transactional mail. If you use it for domains containing
humans, some of their mail will be rejected. If they are humans who you can force to live with this, more power to you,
go for it. Save rates will be better for p=quarantine (then again, there is no spam so spammy that no user will save it,
so p=quarantine is also notably less protective.)
