DMARCPROBLEM.comDMARC Record Analysis

Disclaimer

This DMARC checker is for policy, alignment, and reporting-tag analysis only. Results can be affected by live DNS changes, inherited subdomain policy, and how individual receivers process DMARC reports.

DMARC policy changes can have immediate delivery consequences, especially when moving from monitoring to quarantine or reject.

Before changing a DMARC policy, reporting address, alignment mode, or subdomain policy, independently verify the result and obtain approval from your relevant DNS and email administrators.

An incorrect or overly strict DMARC record can cause legitimate mail to be quarantined or rejected if SPF or DKIM alignment is not working as intended.
