If instead S/MIME opaque is selected, the signature is recognized valid by the sender account, invisible by others. STEPS TO REPRODUCE 1. Select S/MIME signing mode from settings 2. Set an X.509 certificate for signing 3. Send signed email OBSERVED RESULT When sending a signed email in the S/MIME format, the email is marked to have "invalid signature" when read. If instead S/MIME opaque is selected, the signature is recognized valid by the sender account, invisible by others.
