According to information from the
KMail pages, it should be a simple matter of copy/paste. Here's the relevant part of the page:
Code:
Eudora Lite/Eudora Pro
Eudora uses the mbox format in its mail files. To use them with KMail, make sure that your Eudora mailboxes have been compacted, then copy the .mbx files
(Windows® Eudora) or Eudora mailbox files (Mac® Eudora) to your ~/Mail directory. You don't need to copy the index files. Once you start KMail, the mailboxes
should appear in the Folders pane and the messages should be accessible in the Headers pane.
