DMARC Generator

Configure the final protective shield for your domain.
Decide what happens to emails that fail the SPF or DKIM check.

Which policy? (What to do on failure?)

Observe (none)

Lets all emails through, even forged ones. Optimal for starting to check via reports whether everything is running correctly.

Spam (quarantine)

Emails that fail SPF and DKIM end up in the recipient's spam folder. Good interim solution.

Reject (reject)

Maximum protection. Forged emails are completely rejected and deleted by the recipient.

Receiving servers send XML reports (usually daily) about which emails were sent on your behalf.

Email for aggregated reports (rua)

Highly recommended to find errors in SPF/DKIM.

Email for immediate warnings on errors (ruf) - Optional

Supported by only a few providers.
