Fix this firstThe change with the biggest effect

Strengthen the DMARC policy

Quarantines 25% of mail that fails DMARC, a safe first step: check the reports for legitimate senders that fail before going further.

TypeTXT

Name / Host

_dmarc.openstreetmap.org

Some DNS providers want just “_dmarc” here.

Value

v=DMARC1; p=quarantine; pct=25; rua=mailto:openstreetmap-d@dmarc.report-uri.com; adkim=r; aspf=r

Replaces

v=DMARC1; p=none; rua=mailto:openstreetmap-d@dmarc.report-uri.com

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

MXCan servers find your inbox?Only one MX hostInfo

Info: Only one MX host
All mail for openstreetmap.org goes to a.mx.openstreetmap.org. Most hosted providers make that one name highly available; if you run your own server, consider a backup MX.

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 openstreetmap.org 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 openstreetmap.org.

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.

BIMICan inboxes show your logo?No BIMI recordInfo

Info: No BIMI record
No BIMI record at default._bimi.openstreetmap.org. 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 issues foundPass

Nothing to report.

TLS-RPTWill you hear about failures?TLS-RPT is configuredPass

Pass: TLS-RPT is configured
TLS reports will be sent to mailto:openstreetmap-d@tlsrpt.report-uri.com.

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.openstreetmap.org

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