For years, Yahoo has rejected mailing list email with From lines from domains with a DMARC record with p=reject or p=quarantine. We identified a Yahoo policy change in early November, affecting handling of mailing list email from domains with a DMARC record of p=none. Previously, they would accept mailing list emails sent from these domains without having to re-write the From line. Since the policy change, they have started bouncing those messages.
Thanks Mark, good to know.
Our policy had been to not re-write the From lines of emails sent from p=none domains. In light of this change and to clear up other confusion, we now re-write From lines from domains that have any DMARC record. Which, alas, ends up being most of our list traffic.
Interesting. It does seem a shame to do as such, given that when operating within published standards means one shouldn't have to, but I guess when you want to ensure email is delivered...
