Version: 2.0.89 (using KDE 4.6.0) OS: Linux Filters are correctly applied when KMail2 is running, but if KMail2 is closed and Akonadi fetches more mail then when KMail2 is opened again the filters are not applied to the new mail. Workaround is to manually select and apply filters, or to disable Akonadi from fetching mail while KMail2 is closed. Reproducible: Didn't try
It's fixed now in 4.6 Could you re-test it please ? and reopen if necessary Thanks
