Thunderbird 102.0.1 (64-bit) Mac - Digital Signing - Send Message Error
I have three accounts with sign/encrypt certificates. Prior to the update just now, they worked fine, and have for several years. Now after the update, when I try to send an email I get an error message: Sending of the message failed. Unable to sign message. Please check that the certificates specified in Mail & Newsgroups Account Settings for this mail account are valid and trusted for mail.
I get these messages in all three accounts with certificates. I checked the settings, and the certificates are correct.
Fixed. For some unknown reason 102 was missing an intermediate certificate.Read this answer in context 👍 0
