Version: KMail 1.8.1 (using KDE KDE 3.4.1) Installed from: Fedora RPMs OS: Linux First off, I am running a build from the kde-redhat project. There was no option to select kde-redhat builds, so I selected Fedora RPMs earlier. kdepim version is kdepim-3.4.1-1.3.fc3.kde. I have a Thawte free email certificate that was exported from Firefox and then imported to kde via the kde control center ( Note that kde does not work with the certificate generation from the thawte site, so I had to use Firefox ). Although the certificate has been imported into the control centre -> security&privacy -> crypto -> your ceritificates page ... the certificate does not appear in kmail. That is, from kontact -> Configure kmail -> <then select one of my identities> -> Modify -> cryptography -> s/mime signing certificate ... the list is empty. One thing that I find curious, and possible the reason why the list is empty: From within Control centre -> security&privacy -> crypto -> your ceritificates page ... even though it shows my free thawte email certificate ( with a Common Name of "Thawte Freemail Member" ), the column "Email Address" is blank .. which is probably the reason why kmail does not list the certificate ?? I also tried: Control centre -> security&privacy -> crypto -> authentication -> Default Certificate -> .. then selected my certificate, which is: "/CN=Thawte Freemail Member/emailAddress=xxxxx@yyyyy.com"
Just realised this now ... the list is empty for s/mime signing certificate .... but the list for s/mime encryption certificate is NOT empty. Having said that, the free certificate from thawte is supposed to be available for signing as well.
Thank you for taking the time to file a bug report. KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2. We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
