What is the Email Security Analyzer?
Looks up a domain's SPF, DMARC, and MX records and flags the specific gaps that let attackers send email that appears to come from that domain.
How it works
It queries DNS for the domain's TXT records and picks out the one starting with v=spf1, queries TXT records on _dmarc.<domain> for one starting with v=DMARC1, and fetches the domain's MX records separately. Each result is checked against its expected prefix and shown alongside a plain-language note on what it means — for example, whether DMARC is set to none (monitor only), quarantine, or reject.
SysAdmin & security use cases
- Check a domain right after setting up SPF or DMARC to confirm the records actually took effect.
- Audit a domain you just acquired or inherited for missing or weak email authentication.
- Diagnose why legitimate email is landing in spam by checking whether SPF and DMARC line up.
- Confirm MX records are pointed at the right mail provider after a migration.
