Tools

check_email_security
Checks whether a domain can be email-spoofed, using public DNS only. Verifies SPF (including the RFC 7208 multiple-record permerror), DMARC policy and reporting, MX, and DKIM at common selectors. Returns a graded report with concrete fixes. Accepts a bare domain, a URL, or an email address. Nothing is sent to the domain.
shallow
compare_email_security
