Enter your school's domain to check its email authentication records (SPF, DKIM, DMARC).
This tool performs live DNS lookups on publicly available records. It does not access any private data or email content.
Why Email Security Matters for Schools
Without proper email authentication, attackers can send emails that appear to come from your school — targeting parents with fake fee payment requests, phishing teachers for credentials, or impersonating administrators.
- SPF — Specifies which servers can send email for your domain
- DKIM — Digitally signs your emails to prove authenticity
- DMARC — Tells receivers what to do with failed authentication
- MX — Mail exchange records for receiving email
