recovering mail archive under kmail
My HD crashed, and with it my mail archive which I held in KMail. Fortunately, I had a backup of these files. I reinstalled a new version of Slackware, and I decided to restore the mail directory from backup. However, KMail turns out to be configured differently, and it has a config file with only the standard folders in it, so I cannot simply replace the mail directory. How can I recover the rich array of folders which I had, without having to import them one by one?
