DMARC Generator - Set DNS Records Professionally

🛡️ DMARC Record Generator from IPWarmup.blog

Build a DMARC TXT record that tells mailbox providers what to do with mail that fails SPF/DKIM — and where to send reports.

Domain

Policy (p=) what to do on failure none — monitor only quarantine — send to spam reject — block delivery

Subdomain policy (sp=) same as domain policy none quarantine reject

DKIM alignment (adkim=) relaxed — subdomains OK strict — exact domain match

SPF alignment (aspf=) relaxed — subdomains OK strict — exact domain match

Percentage applied (pct=) ramp up enforcement gradually

100%

Aggregate report email (rua=) daily XML summaries

Forensic report email (ruf=) optional, per-failure detail

DNS TXT record

Start with p=none for a few weeks to review aggregate reports, then move to quarantine, then reject once you've confirmed all legitimate senders pass SPF/DKIM.
