Mailquorum
Read DMARC aggregate XML offline, separate legitimate senders, measure SPF and DKIM alignment, and stage enforcement with evidence.
Focused field tools
Interpret report metadata, source rows, counts, disposition, DKIM, and SPF results.
Distinguish authentication pass from identifier alignment.
Count DNS-triggering mechanisms and stay within the lookup limit.
Track selector, key ownership, signing domain, rotation, and failure evidence.
Recognize legitimate forwarding and mailing-list transformations.
Separate owned infrastructure, vendors, unknown senders, and abuse.
Mailquorum analyzes imported records and entered policy assumptions; it does not query DNS, receive reports, validate cryptographic signatures, or change mail policy. Verify current DNS, selectors, forwarding behavior, legitimate sources, and enforcement impact before publishing changes.
