Version: (using KDE 4.2.2) OS: Linux Installed from: SuSE RPMs I sorted the mails by sender in the INBOX (which contains more than 16000 messages), selected about 50 consecutive mails, and stared to move the to another folder. Kmail wrote "Moving messages..." onto the status field (bottom left corner of the window), but the it started to use the hard drive heavily, get unresponsive (compiz made it gray), and virtually did nothing, not even showing a progress bar. I killed it, and realized, that it was trying to copy ALL the messages (not just the selected ones) from the INBOX to the destination folder, or something like that, at least the local copy of the destination dimap folder contained thousands of mails after killing kmail.
I've forgotten to mention that I use Courier IMAP server.
Maybe related to bug #185147 (at least for the unresponsiveness).

I see this problem too

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.
