Version: 1.13.0 (using 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2)), Kubuntu packages) Compiler: cc OS: Linux (i686) release 2.6.32-11-generic I mark all my mails in the "local" IMAP account's spam folder, and forward them ("f"). A new window pops up with the selected mails in the attachment list. Then, I go to another accounts spam folder, mark all mails and drag'n'drop them to the new mail. After sending this mail, the mails where I pressed "f" upon get marked as being forwarded, but the mails I dragged into the attachment list are not being marked as such. So, the bug/cosmetic issue here is, that mails dragged into a mail to be forwarded are not marked, but only mails on which "forward" has been called.
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.
