MXCan servers find your inbox?No MX recordsFailing
  • Fail: No MX records

    ttvnw.net has no MX records and no A/AAAA fallback, so it cannot receive mail, including bounces and DMARC reports. Publish an MX record pointing at your mail provider.

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 ttvnw.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 ttvnw.net.

DMARCWhat happens to fakes?DMARC uses strict alignmentInfo
  • Info: DMARC uses strict alignment

    With adkim=s or aspf=s the DKIM d= domain or the bounce domain must equal the From domain exactly; a subdomain is not enough. Third-party senders that sign or bounce from a subdomain (or their own domain) will then fail DMARC unless they are configured to use your exact domain.

AlignmentDoes it match your From?DKIM alignment is unlikely under adkim=sNeeds attention
  • Warning: DKIM alignment is unlikely under adkim=s

    This is a heuristic. No DKIM key was found at ttvnw.net under the selectors we probed, and adkim=s requires the signing d= domain to equal ttvnw.net exactly. If your mail is signed with a provider's domain or a subdomain, DKIM will not align. A key may exist under a selector we did not try; send a test message to confirm.

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

    No BIMI record at default._bimi.ttvnw.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.ttvnw.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.ttvnw.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

Enable DKIM for Google Workspaceinstruction

Google Workspace generates the DKIM key for each account, so the exact record must come from Google Workspace. Without DKIM, mail it sends for ttvnw.net cannot pass DMARC through DKIM.

Applies to: google._domainkey.ttvnw.net

  1. In Google Workspace, enable DKIM signing for ttvnw.net: Generate the key in Admin console > Apps > Gmail > Authenticate email, then publish the TXT record shown there. Publish exactly the record Google Workspace shows (TXT or CNAME) at the host name it gives, then turn signing on. Instructions: https://support.google.com/a/answer/174124

Set up a TLS report addressinstruction

Sending servers will report TLS failures when delivering to ttvnw.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.ttvnw.net

  1. Pick an address that will receive TLS reports: a mailbox you read (for example tls-reports@ttvnw.net, created first) or a TLS reporting service. 2. Publish a TXT record at _smtp._tls.ttvnw.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.ttvnw.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://ttvnw.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.ttvnw.net with v=BIMI1, l= set to the logo URL and a= set to the certificate URL.
