Reduce SPF DNS lookups

Evaluating SPF for qq.com takes 8 DNS lookups including nested includes; receivers stop at 10 and fail SPF. No detected sending service accounts for these includes; remove each one you no longer send through: spf.mail.qq.com. Changes: Replaced ~all with -all so mail from servers not listed is rejected.

TypeTXT
Name / Host
qq.com

Some DNS providers want “@” here instead of the full domain.

Value
v=spf1 include:spf.mail.qq.com -all
Replaces
v=spf1 include:spf.mail.qq.com ~all

How to apply it

  1. Sign in where your domain’s DNS is managed. This is often where you bought the domain, such as Cloudflare, GoDaddy or Namecheap.
  2. Find the existing TXT record with that name and replace its value.
  3. Save, then come back and re-check. DNS changes can take up to a few hours to show.

SPFWho may send as you?SPF is close to the 10-lookup limitNeeds attention
  • Warning: SPF is close to the 10-lookup limit

    Evaluating the SPF record for qq.com needs 8 of the 10 allowed DNS lookups. Adding one more service, or a provider growing its own record, will break SPF.

    How to fix this
  • Info: SPF ends in softfail (~all)

    "~all" is common and works well with DMARC. "-all" is stricter; switch when you are sure every sender is listed.

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 qq.com 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 qq.com.

DMARCWhat happens to fakes?DMARC policy is quarantine; consider rejectInfo
  • Info: DMARC policy is quarantine; consider reject

    Failing mail goes to spam rather than being refused. When reports show no legitimate failures, reject gives the strongest protection.

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

    No BIMI record at default._bimi.qq.com. 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.qq.com. MTA-STS (RFC 8461) makes sending servers require TLS and a valid certificate when delivering to you, which blocks downgrade attacks.

    How to fix this
TLS-RPTWill you hear about failures?No TLS-RPT recordInfo
  • Info: No TLS-RPT record

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

Other fixes

Strengthen the DMARC policyTXT

Rejects mail that fails DMARC, the strongest protection against spoofing.

TypeTXT
Name / Host
_dmarc.qq.com

Some DNS providers want just “_dmarc” here.

Value
v=DMARC1; p=reject; rua=mailto:mailauth-reports@qq.com; adkim=r; aspf=r
Replaces
v=DMARC1; p=quarantine; rua=mailto:mailauth-reports@qq.com

Publish the MTA-STS recordTXT

Tells sending servers that qq.com publishes an MTA-STS policy at https://mta-sts.qq.com/.well-known/mta-sts.txt. Change the id whenever the policy file changes.

TypeTXT
Name / Host
_mta-sts.qq.com

Some DNS providers want just “_mta-sts” here.

Value
v=STSv1; id=202610040202

Host the MTA-STS policy filepolicy-file

Serve this file over HTTPS with a valid certificate for mta-sts.qq.com. It lists your MX hosts and starts in testing mode; switch to mode: enforce once TLS-RPT reports show no failures.

Location
https://mta-sts.qq.com/.well-known/mta-sts.txt
Contents
version: STSv1
mode: testing
mx: mx3.qq.com
mx: mx2.qq.com
mx: mx1.qq.com
max_age: 604800

Set up a TLS report addressinstruction

Sending servers will report TLS failures when delivering to qq.com, 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.qq.com

  1. Pick an address that will receive TLS reports: a mailbox you read (for example tls-reports@qq.com, created first) or a TLS reporting service. 2. Publish a TXT record at _smtp._tls.qq.com 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.qq.com

  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://qq.com/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.qq.com with v=BIMI1, l= set to the logo URL and a= set to the certificate URL.
