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.
