By default, CanIt-Domain-PRO does not apply DMARC policies. To make CanIt-Domain-PRO start applying DMARC policies for your domain, you need to click on Rules and then DMARC rules:
CanIt-Domain-PRO can apply four possible actions in response to DMARC policies. The actions are:
- Ignore: no DMARC checking is done whatsoever.
- Dry-Run: the DMARC policy is checked, but not enforced. The only thing CanIt-Domain-PRO does is to log the DMARC policy results in the list of tests that are hit.
- Quarantine: if the DMARC policy specifies “reject” or “quarantine”, the message is quarantined (tagged in a tag-only stream.)
- Enforce: the DMARC policy is enforced: If the DMARC policy specifies "reject", the message is rejected. If it specifies "quarantine", the message is quarantined (tagged in a tag-only stream.)
To set a DMARC action for a domain:
- Enter the domain name in the Domain box. If you use a single asterisk for the domain name, then that action applies to any domains that do not have a specific entry.
- Select the appropriate action in the Action column.
- Click Submit Changes.
In the example in the figure, we see that by default, CanIt-Domain-PRO will check the DMARC record in dry-run mode only. However, for the two domains interfax.net and yahoo.com, CanIt-Domain-PRO will enforce the DMARC policy.
If an incident results in a "quarantine" DMARC policy, then it is annotated with the word "DMARC" with a red slash through it in the quarantine display, like this:
This indicates a possibly forged message. Additionally, the "Hold Reason" is set to DMARC.
By default, only realm administrators have permission to make DMARC rules.
