Version: 1.9.1 (using KDE KDE 3.5.1) Installed from: Ubuntu Packages When receiving encrypted e-mails from my boss, decryption works when I am the only recipient, but not when my project leader is in copy. Though, the decryption works fine using Thunderbird/Enigma, which uses the same backend (OpenPGP). That allows me to pinpoint the problem to KMail, and my guess is that KMail tries to decrypt using the wrong key (may the key from the person in CC: rather than the one in To:?). If there is a way to compile KMail on its own (and not to check out the full KDE tree), please let me know, and let me know the branch to use too, this way I kind work on that problem when work gets boring! Cheers, Hervé (a KMail fan).
You can checkout the branches/KDE/3.5/kdepim module. AFAIK checking out the kmail directory only is not sufficient since it relies on some libraries under kdepim . Then you should run : "make -f Makefile.cvs && ./configure --enable-debug && make" . Good luck debugging and thanks:)
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.
