Version: 1.13.1 (using KDE 4.4.1) OS: Linux Installed from: Ubuntu Packages Currently the search function of kmail is limited to search in "All local Folders" or in specific folder. There is no way to make a application wide search including IMAP accounts for example. I got quite a few email accounts (also several IMAP) and don't always remember which one contains the message I am searching for. I think having another option for searching all mail would be very helpful.
