All checks

MXCan servers find your inbox?Mail relies on implicit A recordNeeds attention
  • Warning: Mail relies on implicit A record

    nflxvideo.net has no MX records, so senders fall back to its A/AAAA address (RFC 5321 implicit MX). Publish an explicit MX record, or a null MX ("0 .") if the domain should not receive mail.

SPFWho may send as you?No issues foundPass

Nothing to report.

DKIMAre your emails signed?No DKIM key found for the common selectorsNeeds attention
  • Warning: No DKIM key found for the common selectors

    None of the 47 selectors probed under nflxvideo.net publish a DKIM key. DNS cannot list selectors, so a key under a custom selector may exist: find the s= value in the DKIM-Signature header of a message you sent and check that selector. If DKIM is not set up, enable it at each service that sends mail for nflxvideo.net.

DMARCWhat happens to fakes?No issues foundPass

Nothing to report.

AlignmentDoes it match your From?SPF alignment is unknownInfo
  • Info: SPF alignment is unknown

    The SPF record of nflxvideo.net authorizes no sender (no +ip4, +ip6, +a, +mx, +exists or +ptr term, include of a record that has one, or +all before all), so SPF never passes and cannot align. That is correct for a domain that sends no mail; otherwise DMARC depends on DKIM alone.

BIMICan inboxes show your logo?No BIMI recordInfo
  • Info: No BIMI record

    No BIMI record at default._bimi.nflxvideo.net. BIMI is optional: it shows your logo next to your mail in supporting inboxes once DMARC is enforced.

    How to fix this
MTA-STSIs mail to you encrypted?No MTA-STS recordInfo
  • Info: No MTA-STS record

    No MTA-STS record at _mta-sts.nflxvideo.net. MTA-STS (RFC 8461) makes sending servers require TLS and a valid certificate when delivering to you, which blocks downgrade attacks.

TLS-RPTWill you hear about failures?No TLS-RPT recordInfo
  • Info: No TLS-RPT record

    No TLS reporting record at _smtp._tls.nflxvideo.net. TLS-RPT (RFC 8460) tells senders where to send daily reports about failed encrypted deliveries to you.

    How to fix this

How to fix it

Set up a TLS report addressinstruction

Sending servers will report TLS failures when delivering to nflxvideo.net, which you need before enforcing MTA-STS. The address must accept TLS reports; a DMARC report address does not necessarily do so.

Applies to: _smtp._tls.nflxvideo.net

  1. Pick an address that will receive TLS reports: a mailbox you read (for example tls-reports@nflxvideo.net, created first) or a TLS reporting service. 2. Publish a TXT record at _smtp._tls.nflxvideo.net with the value v=TLSRPTv1; rua=mailto:<that address>.

Prepare BIMIinstruction

BIMI shows your logo next to messages in supporting inboxes, but only for mail that passes DMARC under an enforced policy.

Applies to: default._bimi.nflxvideo.net

  1. Enforce DMARC first: p=quarantine or p=reject at 100% (no pct below 100). 2. Convert your logo to an SVG Tiny PS file and host it over HTTPS, for example https://nflxvideo.net/bimi/logo.svg. 3. For Gmail and Apple Mail, obtain a VMC or CMC certificate for the logo. 4. Publish a TXT record at default._bimi.nflxvideo.net with v=BIMI1, l= set to the logo URL and a= set to the certificate URL.
