DMARC policy too weak for bulk sending

Your DMARC policy is p=none. For bulk senders, Gmail and Yahoo expect a stronger policy (quarantine or reject).

Why it matters

p=none means "monitor only" — receivers don't quarantine or reject on alignment failure. For bulk/marketing, providers now expect you to move to p=quarantine or p=reject once you're confident in SPF/DKIM.

How to fix it

Confirm SPF and DKIM are aligned with your From domain and that you're not seeing unexpected failures in DMARC reports.

Change p=none to p=quarantine first; monitor for a while, then consider p=reject.

Keep rua= (and optionally ruf=) so you get reports and can react if something breaks.
