1Upgrade your DMARC policy from p=quarantine to p=reject for full blocking
With p=quarantine, spoofed emails are sent to spam instead of being blocked outright. Some recipients still check spam folders, and sophisticated attacks can be flagged as legitimate by users. p=reject ensures fraudulent emails never reach any folder.
