A monitoring DMARC policy allows you to observe and collect data on your domain's email authentication results without taking restrictive actions, such as blocking or quarantining messages that fail DMARC checks. This approach is beneficial when first implementing DMARC, so you can review and adjust your setup before enforcing stricter policies.
How Do I Configure a Monitoring DMARC Policy?
To set up a DMARC policy for monitoring, use `p=none` in your DMARC record. This tells email receivers to generate reports on your email traffic without affecting message delivery.
Example DMARC Record for Monitoring:
v=DMARC1; p=none; sp=none; adkim=s; aspf=s; pct=100; ri=86400
- **p=none**: No enforcement, only data collection.
- **sp=none**: No enforcement for subdomains.
- **adkim=s** / **aspf=s**: Strict alignment (or use `r` for relaxed if preferred).
- **pct=100**: Applies to all messages.
- **ri=86400**: Daily reporting interval.
Why Start with a Monitoring Policy?
This approach lets you analyze email traffic and understand who is sending emails on your behalf. It gives you time to make any necessary changes before shifting to a more protective policy, like `quarantine` or `reject`.
