What you’re seeing
- Invoices or receipts from your billing platform suddenly bounce or land in customers' spam.
- Bounce messages mention a DMARC policy rejection for your domain.
- Mail from the office scanner, website contact form or CRM stops arriving.
- DMARC reports list failures from services you recognize as your own vendors.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- A third-party service sends as your domain without DKIM signing for your domain or aligned SPF.
- Your SPF record requires more than ten DNS lookups, so receivers treat it as a permanent error.
- The policy moved to quarantine or reject before DMARC reports were reviewed to identify every legitimate sender.
- A copier or scanner relays mail through a server that isn't authorized to send for your domain.
- Messages forwarded through mailing lists or recipients' own forwarding rules fail alignment once the policy is strict.
Why it matters
DMARC enforcement is the right goal: it stops criminals from sending email that looks like it comes from you. Turned on too quickly, though, it blocks your own invoices, quotes, receipts and system notifications, often without anyone noticing until customers complain or payments slow down. Rolling the policy back reopens the door to spoofing. The fix is to authenticate every legitimate sender so enforcement can stay in place.

Frequently asked questions
Should we just turn DMARC enforcement back off?
That stops the bounces but leaves your domain open to spoofing again. A better approach is to bring the failing services into compliance and keep the protection.
How do we find every service that sends email as us?
DMARC reports show every source using your domain. An engineer reviews them with you to separate legitimate vendors from impersonators.
