No DKIM key found under 79 common selectors.

Either DKIM signing is off, or it uses a selector we did not probe. Without DKIM, forwarded mail and anything that breaks SPF fails DMARC.

Do this: turn on DKIM at your mail provider and at every third-party sender, then add the selector names when monitoring so they are verified daily. If DKIM is already on with an uncommon selector, add it to the check.

# Fix email authentication for notion.so

Measured by MailAuthWatch on 17 Oct 2026 from public DNS. Grade C (70/100).

## Tasks, in order of impact
### 1. No DKIM key found under 79 common selectors.
Why: Either DKIM signing is off, or it uses a selector we did not probe. Without DKIM, forwarded mail and anything that breaks SPF fails DMARC.
Turn on DKIM signing at the mail provider and at every third-party service that sends as this domain (CRM, newsletter tool, help desk).
Publish the selector records each service shows. If DKIM is already on with a selector not in the common list, add that selector to the MailAuthWatch check instead.

## 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 Cloudflare, stop and say exactly what access you need.

## Verify
  dig +short TXT notion.so
  dig +short TXT _dmarc.notion.so
Then open https://www.mailauthwatch.com/check/notion.so?fresh=1 and confirm:
  DKIM found. 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.

Final mechanism: ~all

OK No problems detected.

DKIM Not found

DKIM selectors cannot be listed from DNS, so 79 selectors used by common providers were probed. "Not found" means none of those selectors exist; the domain may still sign with a custom selector.

WarningNo DKIM key found under 79 common selectors. If you know your selector, add it to the check; if you have no DKIM at all, enable it at your mail provider.

DMARC OK

v=DMARC1; p=quarantine; pct=100; rua=mailto:re+1b3a27dd30bc@inbound.dmarcdigests.com;

Policy: p=quarantine
Applies to: 100% of failing mail
Aggregate reports: mailto:re+1b3a27dd30bc@inbound.dmarcdigests.com

NotePolicy is p=quarantine. p=reject is the strongest protection once you are confident all senders are aligned.

Mail exchange and extras

NoteNo MX records: this domain does not receive mail. If it also never sends mail, publish "v=spf1 -all" and a p=reject DMARC record to stop spoofing.

MTA-STS: Not published optional: enforces TLS for inbound mail
TLS-RPT: Not published
BIMI: OK v=BIMI1; l=https://vmc.digicert.com/ae66f82a-dd47-4f08-9fd9-fd865f1d0b30.svg; a=https://vmc.digicert.com/ae66f82a-dd47-4f08-9fd9-fd865f1d0b30.pem

How the grade is calculated

Score 70/100. SPF present and valid. SPF ends with ~all. DMARC present and valid. DMARC policy is quarantine. 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.
