Email Spoofing Check
Can attackers impersonate your domain?
What this test checks
DMARC policy, coverage, subdomain inheritance and supporting SPF configuration. DKIM is not marked missing when no selector is known.
Why this matters
A visible From address can be forged. DMARC gives compatible receiving systems domain-owner guidance when SPF or DKIM does not align.
How to fix common problems
Start with a valid DMARC monitoring policy and reports. Align legitimate senders, then gradually enable quarantine or reject.
FAQ
Can this prove nobody can spoof my domain?
No. It measures the protection requested from DMARC-aware receivers; it never makes an absolute guarantee.
Does this tool send a test email?
No. It only analyzes public DNS and performs no message delivery.
