DMARCPROBLEM.comDMARC Record Analysis

Validation and Liability

This DMARC checker inspects the policy record at the domain's _dmarc host and highlights policy, alignment, percentage rollout, and reporting-tag issues. It does not process aggregate report XML files or prove how every receiver will handle a specific message.

DMARC enforcement depends on SPF or DKIM alignment. A syntactically valid p=quarantine or p=reject policy can still cause delivery problems if legitimate senders are not aligned first.

Before changing p, sp, pct, rua, ruf, adkim, or aspf, confirm current authentication results from real mail, review reports where available, and obtain approval from your DNS and email administrators.

An incorrect DMARC policy can hide useful reporting, fail to protect the domain, or ask receivers to quarantine or reject legitimate mail before SPF and DKIM alignment are ready.
