Hi Joseph, You have to set up Your certificate for Your Mail-Account: Edit/Mail&Newsgroups Account Settings Then select Your Mail-Account --> Security There You should select Your certificate.
At this stage I get another error message, when creating a digitally signed message: "Sending of message failed: You specified that this message should be digitally, but the application either failed to find an encryption certificate to include in the signed message, or the certificate has expired" Well, the cert. will expire on June, 16, so this should not be the problem, I hope. On the other hand, the cert. provider (web.de) does not support Mozilla-based Browsers. So my problem might be due to web.de, but I remember, that it had worked with previous versions. I don't know. I hope this helps You in any way. Michael
