Fix this firstThe change with the biggest effect

Publish a DMARC record

Starts DMARC in monitoring mode (p=none), so you can see who sends as xiaomi.net before enforcing a policy. Move to quarantine once the reports show only your own services.

TypeTXT
Name / Host
_dmarc.xiaomi.net

Some DNS providers want just “_dmarc” here.

Value
v=DMARC1; p=none; adkim=r; aspf=r

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. Add a new TXT record with the name and value above.
  3. Save, then come back and re-check. DNS changes can take up to a few hours to show.

All checks

MXCan servers find your inbox?MX host does not resolveFailing
  • Fail: MX host does not resolve

    mx2.mxmail.xiaomi.com has no A or AAAA record, so senders cannot deliver to it. Fix the hostname or remove the MX record.

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 xiaomi.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 xiaomi.net.

DMARCWhat happens to fakes?No DMARC recordFailing
  • Fail: No DMARC record

    There is no v=DMARC1 TXT record at _dmarc.xiaomi.net. Without DMARC, receivers have no policy for mail that fails SPF and DKIM, and Gmail and Yahoo require one for bulk senders. Start with p=none and a rua address to collect reports.

    How to fix this
AlignmentDoes it match your From?SPF alignment is unknownInfo
  • Info: SPF alignment is unknown

    The SPF record of xiaomi.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.xiaomi.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.xiaomi.net. 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.xiaomi.net. TLS-RPT (RFC 8460) tells senders where to send daily reports about failed encrypted deliveries to you.

    How to fix this

Other fixes

Publish the MTA-STS recordTXT

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

TypeTXT
Name / Host
_mta-sts.xiaomi.net

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

Value
v=STSv1; id=202610040213

Host the MTA-STS policy filepolicy-file

Serve this file over HTTPS with a valid certificate for mta-sts.xiaomi.net. 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.xiaomi.net/.well-known/mta-sts.txt
Contents
version: STSv1
mode: testing
mx: mx3.mxmail.xiaomi.com
mx: mx1.mxmail.xiaomi.com
mx: mx2.mxmail.xiaomi.com
max_age: 604800

Set up a TLS report addressinstruction

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

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