DMARC
Organizational policy (p): how receivers treat mail that fails aligned DMARC checks — none (monitor only), quarantine (often junk), or reject (block).
Subdomain policy (sp): when set, it applies to hostnames below this domain instead of p; if omitted, subdomains inherit the organizational policy.
pct: share of mail that gets quarantine/reject; 100 = all failing messages (default).
100Aggregate DMARC reports (ZIP/XML). Optional but recommended for visibility.
Forensic (per-failure) reports. Often omitted for privacy or volume.
mmlaccess.com. 300 IN DMARC v=DMARC1; p=reject; sp=reject; pct=100; rf=afrf; ri=86400; fo=1; aspf=s; adkim=s; ruf=mailto:[email protected]; rua=mailto:[email protected]
