kmail2 does not move messages via "drag and drop" nor via "move to folder" into a other folder. As far as I know there is no work around anymore. Well done. BTW: These messages should have been moved by a filter. But the nasty filter bug is still there. Some message are moved some are not.
Looks like that this is only true for messages marked as spam.
Sorry, I have another comment. After restarting kmail2 / kontact, the messages are gone. Seems to be a problem with the display of moved / deleted messages in the message view.
Today spam messages (kmail2 Version 4.10.4) marked with "X-Spam-Flag: Yes" are not moved but copied to the destination folder. I would appreciate less frequent changes and better testing. kmail2 is since month in an pre-ALPHA state. I wish I could get the old working horse kmail 1 back.
"I would appreciate less frequent changes and better testing. kmail2 is since month in an pre-ALPHA state. " => as it's pre-alpha for you why do you use it .??????? Please go back to kmail 1 :) it's better for you and for me, not necessary to read this type of comment. Regards
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
