commsharbor_email_security_check
shallowcom.commsharbor/commsharbor · Verify this server
Check whether someone can send email as a domain: SPF, DKIM in common selectors, DMARC, MX, MTA-STS and BIMI, with a 0-100 score and the fixes, most severe first. Public DNS only. Free, no account. The same domain is served from memory for 10 minutes. A network can run 30 new checks per day. DKIM is looked up in common selectors only; `dkim_not_found` does not prove that no key exists. `incomplete: true` means a DNS answer failed and the score can be lower than the real one; `unread` names those parts, and a failed query never becomes a missing finding.
