DMARC is sitting at p=none.

You are collecting reports and enforcing nothing, so anyone can still send as you. Gmail and Yahoo accept p=none from bulk senders, but it protects nobody.

Do this: move to p=quarantine; pct=25 for two weeks, watch the reports, then step to pct=100 and p=reject.

## Tasks, in order of impact
### 1. DMARC is sitting at p=none.
Why: You are collecting reports and enforcing nothing, so anyone can still send as you. Gmail and Yahoo accept p=none from bulk senders, but it protects nobody.
Replace TXT record:
  _dmarc.live.com  TXT  v=DMARC1; p=quarantine; pct=25; sp=quarantine; rua=mailto:rua@dmarc.microsoft; ruf=mailto:ruf@dmarc.microsoft; fo=1
Only after DKIM is verified working (see the DKIM task if present). Hold for 14 days, review reports, then pct=100, then p=reject.
Azure DNS CLI/API (adjust identifiers):
  az network dns record-set txt add-record -g $RESOURCE_GROUP -z live.com -n _dmarc -v "v=DMARC1; p=quarantine; pct=25; sp=quarantine; rua=mailto:rua@dmarc.microsoft; ruf=mailto:ruf@dmarc.microsoft; fo=1"

## Rules
- Publish exactly one SPF record; never add a second v=spf1 TXT.
- Do not remove any include: or ip4: you cannot account for; mail may depend on it.
- Do not set DMARC to p=reject in one step; stage through p=none → quarantine → reject.
- Show the planned DNS changes as a diff (record, old value, new value) before applying them.
- If you cannot access Azure DNS or Microsoft 365, stop and say exactly what access you need.

## Verify
  dig +short TXT _dmarc.live.com
  dig +short TXT live.com
Then open https://www.mailauthwatch.com/check/live.com?fresh=1 and confirm:
  DMARC p=quarantine. Target grade: A.

## Report back
List each record you changed (name, type, old value, new value), what you verified, and anything you could not do.

DKIM OK

DKIM selectors cannot be listed from DNS, so 79 selectors used by common providers were probed.

Selector	Key	Record
`selector1`	RSA 2048-bit OK	`v=DKIM1;k=rsa;p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAvWyktrIL8DO/+UGvMbv7cPd/Xogpbs…`

DMARC OK

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

Policy: p=none · subdomains sp=quarantine
Applies to: 100% of failing mail
Aggregate reports: mailto:rua@dmarc.microsoft

WarningPolicy is p=none: you receive reports but spoofed mail is still delivered. Move to p=quarantine, then p=reject, once reports show legitimate mail passing.

Mail exchange and extras

OK No problems detected.

MTA-STS: OK v=STSv1; id=20190225000000Z;

BIMI: Not published optional: brand logo in inboxes, requires p=quarantine or reject

How the grade is calculated

Score 80/100. SPF present and valid. SPF ends with ~all. DKIM found (1 selector). DKIM key is 2048-bit or stronger. DMARC present and valid. DMARC policy is none (monitoring only). DMARC aggregate reporting enabled. SPF contributes up to 35 points, DKIM up to 25, DMARC up to 40 (policy strength and reporting). Any critical issue caps the grade at C. Lookups that failed are shown as "not measured" and never counted as missing.
