What this means
- • No DMARC record published (_dmarc). Receivers have no policy to apply.
- • SPF ends with ~all (softfail): acceptable while observing, aim for -all in the end.
- • No DKIM key found on the common selectors (the domain may use non-standard selectors).
- • No MTA-STS (_mta-sts): inbound SMTP connections remain exposed to TLS downgrade. Recommended alongside DMARC.
- • No TLS-RPT (_smtp._tls): the TLS failures encountered by senders are not reported.
