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.

Any ideas?

Thanks.

Fixed. For some unknown reason 102 was missing an intermediate certificate.
