Fix this firstThe change with the biggest effect

Strengthen the DMARC policy

Quarantines all mail that fails DMARC. Move on to reject once the reports stay clean. Changes: pct applies to sp as well, so a pct=25 ramp would enforce sp=quarantine on only a quarter of subdomain mail. The ramp is skipped to keep subdomains fully protected; p moves to quarantine directly.

TypeTXT
Name / Host
_dmarc.live.com

Some DNS providers want just “_dmarc” here.

Value
v=DMARC1; p=quarantine; rua=mailto:rua@dmarc.microsoft; adkim=r; aspf=r
Replaces
v=DMARC1; p=none; sp=quarantine; pct=100; rua=mailto:rua@dmarc.microsoft; ruf=mailto:ruf@dmarc.microsoft; fo=1

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.

All checks

MXCan servers find your inbox?Only one MX hostInfo
  • Info: Only one MX host

    All mail for live.com goes to live-com.olc.protection.outlook.com. Most hosted providers make that one name highly available; if you run your own server, consider a backup MX.

SPFWho may send as you?SPF ends in softfail (~all)Info
  • 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?DKIM key publishedPass
  • Pass: DKIM key published

    live.com publishes a DKIM key under selector1.

DMARCWhat happens to fakes?DMARC policy is noneNeeds attention
  • Warning: DMARC policy is none

    A none policy only monitors: mail that fails DMARC is still delivered, so anyone can spoof the domain. Once reports show your legitimate senders pass, move to quarantine and then reject.

Other fixes

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