Version: (using KDE 4.2.2) OS: Linux Installed from: Ubuntu Packages kmail has two options for automatically deleting trash: when closing the program, and deletion after X days. It might be good to include a notification if both options are selected. This might cause problems, if the spam filter is in its early learning stage, and classifies many important mail as spam, which are moved to the trash (and deleted later).
Thank you for your feature request. Kmail1 is currently unmaintained so we are closing all wishes. Please feel free to reopen a feature request for Kmail2 if it has not already been implemented. Thank you for your understanding.
Instead of creating a new feature request, please confirm here if the wishlist is still valid for kmail2.
