How do I import e-mail messages from kmail (Linux)?
Make a new folder in kmail and name it inboxmbox. You’ll see a dialogue in which you can save it as an mbox folder. Copy all posts in your kmail inbox folder to the new inboxmbox folder. Exit kmail. Next, copy or move inboxmbox to the subfolder Mail/Local Folders in your profile folder. When you open Thunderbird you’ll see the inboxmbox folder under Local Folders. Copy the messages into your Inbox folder if you like.
