DMARC policy and reporting addresses

Mail administrators can define a policy when they need to prepare the addresses associated with its DMARC reports.

Set a DMARC policy together with its reporting addresses, producing one structured configuration that can be reviewed before use.

How to use

Choose the DMARC policy you want: no action, quarantine, or reject, based on how strictly you want to treat failing mail.
Enter the aggregate report address that should receive DMARC summaries.
Set the percentage of messages to which the policy applies.
Generate the configuration, then review the resulting string before publishing it in DNS.
Clear the form or import a supported text file if you want to start from existing notes.

Example

The sample begins with a quarantine policy, a report address, and a full application percentage. After generating, check the policy structure, the reporting address, and the percentage, without copying those values directly into your DNS.

Input

quarantine
reports@example.com
100

Limits and formats

The tool builds a policy but does not publish it in your DNS zone.
Make sure the reporting address is correct and able to receive reports before using the result.
A strict policy applied too early can affect legitimate mail, so start with monitoring when possible.
Review the generated string with your mail administrator, because syntax details matter.

Where processing happens

The builder runs entirely in your browser, so the chosen policy, reporting address, and percentage stay on your device. Nothing is transmitted, which lets you prepare several versions before publishing the one you select. You can therefore refine the policy text until it matches your intended rollout.

Frequently asked questions

Which policy should I start with?

Start with a no-action policy if you only want to observe, or with quarantine if you are ready to filter. Reject is stricter and deserves a prior check of your legitimate sending streams.

Can the report address be a personal mailbox?

The field expects an aggregate report address. Prefer a dedicated mailbox or service address, and confirm that it accepts DMARC reports before you publish the policy.

Does the percentage need to cover every message?

The percentage controls how much mail is covered by the policy. For a gradual rollout, a lower value helps you observe the effect before applying the policy to all outgoing messages.
