Warning: No DKIM key found for the common selectors
None of the 47 selectors probed under doctolib.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 doctolib.net.

No BIMI record at default._bimi.doctolib.net. BIMI is optional: it shows your logo next to your mail in supporting inboxes once DMARC is enforced.

How to fix it

Enable DKIM for Google Workspaceinstruction

Google Workspace generates the DKIM key for each account, so the exact record must come from Google Workspace. Without DKIM, mail it sends for doctolib.net cannot pass DMARC through DKIM.

Applies to: google._domainkey.doctolib.net

In Google Workspace, enable DKIM signing for doctolib.net: Generate the key in Admin console > Apps > Gmail > Authenticate email, then publish the TXT record shown there. Publish exactly the record Google Workspace shows (TXT or CNAME) at the host name it gives, then turn signing on. Instructions: https://support.google.com/a/answer/174124

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.doctolib.net

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