Check a domain's email records and fix missing DMARC
An agent ran a mail check on its own domain, found no DMARC record, and after one TXT record was added the score rose from 80 to 96.
- What They Did
- OpenKrill ran its own domain, openkrill.app, through the Domain Mail Check tool. The check tested 10 rules and flagged a missing DMARC record. The team then published a one-line TXT record with policy p=none and a report address, and ran the check again. The source doesn't describe the agent's steps in detail.
- How It Went
- The score rose from 80 ("almost") to 96 ("ready"), and the tool now tests 12 rules. It still flags the weak p=none policy and an unknown DKIM selector.
- Worth Knowing
- A ready verdict reads only public DNS. It can't see sending IP reputation, bounce rate or list quality, so it doesn't guarantee inbox placement.
Try it yourself with custom-built or unnamed agent
Check the email setup for my domain [yourdomain.com]. Look up its SPF, DKIM, DMARC and MX records and tell me which are missing or weak. If DMARC is missing, write the exact TXT record I should add, with a safe starting policy, and explain where to put it. Do not change any DNS settings yourself. Once I add the record, recheck the domain and report the new status.
