I have a valid x.509 certificate and am able to send S/MIME signed emails via Thunderbird 128.5.1esr (64-bit) [Windows 10.0.22631.4460).
The private key is stored on a Yubikey. However, the certifying authorities are in the Thunderbird Authorities.
I can send S/MIME signed emails.
Viewing the received email in Gmail (web) correctly shows that email is signed, verified by a known issuer, and provides links to the certificates.
Viewing the same received email in Thunderbird only shows the S/MIME badge/icon when the Yubikey is connected.
Is this intentional behavior? Why doesn't Thunderbird show the S/MIME badge?
