Keep branding separate from transport#
BIMI concerns supported sender-logo display and provider-specific eligibility. MTA-STS concerns a published transport policy. TLS reporting helps operators receive evidence about transport issues. Publishing one record does not activate every layer.
Use the complete setup process#
Follow the relevant specification and your provider’s requirements. Validate the supporting assets and policies, not only the DNS text. A BIMI record alone does not prove logo display, trademark registration or certificate eligibility.
Read diagnostics with their limits#
DomainGuard discovers related TXT records. It does not fetch and certify the hosted policy, issue a certificate or guarantee what a recipient sees. Treat the results as an inventory for a separate deployment and validation workflow.
