BIMICan inboxes show your logo?No BIMI recordInfo

Info: No BIMI record
No BIMI record at default._bimi.theguardian.com. 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?MTA-STS is in testing modeInfo

Info: MTA-STS is in testing mode
Senders report TLS failures (with TLS-RPT) but still deliver. Switch to mode: enforce once the reports are clean.

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

Pass: TLS-RPT is configured
TLS reports will be sent to mailto:tlsreporting@theguardian.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.theguardian.com

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