Version: (using KDE KDE 3.4.0) Installed from: FreeBSD Ports KMail has a nice filtering system, which works well for many common tasks. However, one thing its filters simply can't do (so far as I can currently see) is to copy or move a message into a folder whose name isn't known at filter-creation time. This makes it impossible, or at least extremely awkward, to use a general mail-classifying program such as "ifile" to categorize incoming messages into a large number of categories and file them into folders accordingly. What would be needed for this is the ability to run an external program and use its output to choose a folder; or (given that KMail already has the ability to transform messages by piping them through external programs) maybe the ability to extract a folder name from a message header. I suppose it would be possible to get something akin to this by using virtual folders (named searches), but that seems like a workaround rather than a solution.
Another thing this would allow: a filter, run only when the user explicitly requests it, that moves messages to folders whose names are based on their dates for archival.
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.
