Version: (using KDE 4.1.3) Installed from: Gentoo Packages Steps to reproduce: 1. Delete a message from a disconnected IMAP folder. 2. Undo the deletion. 3. The message reappears, but it is apparently still scheduled for deletion. 4. Synchronize the folder with the server. 5. The message disappears. Possible solution: Unschedule the message for deletion from the server.
The spam is sometimes usefull. Confirmed in kmail 1.11.0 (kde 4.2.0) from opensuse factory repository.
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.
