DMARC policy
DMARC tells receivers how to handle mail that fails domain alignment.
What Chalo checks
Chalo resolves _dmarc TXT and identifies none, quarantine, or reject policy values.
Passing signal
A DMARC record enforces quarantine or reject.
Failing signal
The record is missing or remains in monitoring-only p=none mode.
How to fix it
Begin with reporting, review legitimate traffic, then increase enforcement gradually.
Example configuration
v=DMARC1; p=quarantine; rua=mailto:dmarc@example.com
