Email Security Checker
Check if your domain has SPF, DKIM, and DMARC configured to protect against email spoofing and phishing.

Checking DNS records...
SPF
SPF (Sender Policy Framework) specifies which mail servers are authorised to send email on behalf of your domain. Without it, attackers can send emails that appear to come from your address.
DMARC
DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving servers what to do when SPF or DKIM checks fail. It also enables reporting so you can monitor abuse of your domain.
DKIM
DKIM (DomainKeys Identified Mail) adds a digital signature to outgoing emails, letting recipients verify the message hasn't been tampered with in transit. We check common selectors but your provider may use a custom one.
