You can bulk-update the DNS of the domains in both Mailforge and Infraforge by going to the Domains page > Bulk DNS update

After pressing that button, you will see this screen:

Here, you can select the domains you want to make the update for.

Each record has its own bracket for introduction of details, however for DMARC policy modifier we can select None, Quarantine or Reject.

DMARC Email Modifier: Part of email authentication, DMARC (Domain-based Message Authentication, Reporting, and Conformance) helps prevent unauthorized use of your domain (spoofing).

Domain Forward: A setup that automatically redirects anyone visiting one domain to another. This is useful when you own multiple domains but want all traffic to point to a primary domain.

CNAME Record: A DNS record that creates an alias for a domain name. Instead of pointing directly to an IP address, it redirects queries to another domain name, allowing you to manage resources under one consistent name.
