KMail assists in importing e-mail messages from previously-used applications. Select ‘Extras’->‘Import messages’. KMail currently features import filters for Outlook Express 4, 5 and 6, the mbox format, simple e-mail texts, and Pegasus Mail folders. The import utility can also be started separately by pressing Alt-F2 and entering the command kmailcvt.

Select the corresponding application from the pop-up menu and confirm with Continue. A file or a folder must be provided, depending on the selected type. KMail then completes the process.
