Version: (using KDE 3.5.9) Installed from: Debian testing/unstable Packages KMail should be able to be configured to ignore an IMAP account's shared namespace, i.e., to not use any of the shared folders the server offers. Sometimes the shared folders are HUGE and there is no easy way to make KMail simply not display them. A checkbox next to the shared namespace field in the IMAP account configuration dialog would be the obvious place to configure that.
You can use local subscriptions for this, just right-click your IMAP account in the folder tree.
I am not stupid. I actually tried that. It doesn't help, because this particular IMAP server has many hundreds of folders within the public namespace, and if I choose "Local subscriptions" from the account's context menu (after it has finished synchronizing headers for _all_ of them first!), it opens the "Local Subscription" dialog and starts fetching the folder list. After a few minutes it just says "Loading... (999 matching)" and nothing happens anymore. Once, I waited for over an hour but it never finished. I even tried checking the non-public folders and clicking "OK" while it was still fetching the folder list, in the hope that it would save my selection, but it doesn't seem to save my selection and the public folders do not disappear, not even after a restart of KMail. There should be a way to sidestep the fetching and synchronizing of the public namespace altogether.
FWIW, I have "Show only locally subscribed folders" checked. I also tried checking "Show only subscribed folders", but it didn't make a difference either way.
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.
