MailChimp also doesn't seem to have this issue. Here is a mailchimp header:
Authentication-Results: mta4014.sbc.mail.gq1.yahoo.com;
dkim=pass (ok) header.i=@... header.s=k1;
spf=neutral smtp.mailfrom=@...;
dmarc=fail(p=none sp=quarantine dis=none) header.from=gmail.com;
Note that the mailchimp email was delivered in spite of the DMARC failure.
Larry, both mailserver examples you gave have
p=none policy tags, which
means that the mailbox provider won't take any actions with the emails that fail DMARC. The other two acceptable 'p' tags are 'quarantine' and 'reject'.
