💬 What This Tag Does
The "p" tag is the core of your DMARC record. It tells receiving servers what to do with mail that fails DMARC checks (SPF or DKIM alignment failure). "none" takes no action but allows report collection. "quarantine" places failing mail in the spam/junk folder. "reject" tells the server to refuse delivery entirely.
