What tools check DMARC records?

DMARC verification tools:

dmarcian DMARC Inspector: dmarcian.com/dmarc-inspector - comprehensive policy analysis.

MXToolbox DMARC Lookup: mxtoolbox.com/dmarc.aspx - syntax and policy check.

DMARC Analyzer: dmarcanalyzer.com/dmarc/dmarc-record-check - detailed validation.

Command line:

dig TXT _dmarc.yourdomain.com

What to verify:

Record exists at _dmarc subdomain

Syntax is correct (tags, values)

Policy is intentional (p=none vs p=reject)

Report addresses are valid and will accept reports

Verify DMARC before moving to enforcement. Misconfigurations affect all mail.

Validate your policy declarations. Errors affect how violations are handled.
