From p=none to 96% DMARC pass in 31 days — without breaking a single legit sender.

How an MSP-adjacent monitoring domain went from zero email-auth posture to full p=quarantine enforcement in one reporting cycle, using Mailstinger's laddered enforcement engine.

Some metrics show — while the first 30 days of DMARC reports are being collected from monitoringyournetwork.com's live deployment. This page updates automatically as the data lands.

Before

monitoringyournetwork.com had a vestigial DMARC record at p=none and no DKIM signing in place on outbound mail. The operator had no visibility into who was sending as the domain — by definition, anybody could.

Onboarding (Day 0)

Single CNAME pointed at Mailstinger's hosted slug. SPF, DMARC, MTA-STS, TLS-RPT, and DKIM all delegated. First DMARC aggregate reports flowed in within 24 hours.

First week

Pass rate baseline established. Mailstinger's laddered enforcement engine identified safe to escalate from p=none → p=quarantine pct=10 once aligned-pass exceeded the operator-set threshold.

Day 31

Sustained 96% pass rate at p=quarantine pct=100, with zero false-positives reported on legitimate senders. Override safety gates kept the domain from jumping to p=reject prematurely. TLS-RPT shows encrypted-in-transit posture with clean reports from every major mailbox provider.

Got a finding you don't want to chase?

Hand this off to Mailstinger.

We'll host the policies, rotate the keys, and watch the reports for you. One CNAME and you're done — no spreadsheets, no XML reading, no “what was this DKIM selector again?” moments at 4pm on a Friday.
