DMARC Quarantine

The DMARC Report article explains how the DMARC policy "quarantine" works. When an email fails authentication checks, a quarantine policy instructs receiving servers to deliver the message to the recipient’s spam folder rather than accepting or rejecting it outright. This middle-ground approach helps organisations test DMARC implementations while preventing phishing attacks—an important safeguard when more than 3.4 billion phishing emails are sent daily.
