Email SPF DMARC MX check
apexfaucet.
Check a domain's email authentication setup. Pass ?domain= and get SPF (mechanisms, the all qualifier, DNS-lookup count with include: and redirect= followed up to 10 extra reads, flagged over 10), DMARC (p, sp, pct, rua present) and the MX hosts (the first 5 are checked for an address), each graded good, weak or missing by a written rule returned with the answer. Only the exact _dmarc.<domain> name is read. DKIM selectors cannot be enumerated, so DKIM is not graded. DNS reads at one moment.
