Here are the steps that I used to import my UNIX mail over to Outlook Express.

1. Copy the mail file from your home directory or from /var/spool/ on the UNIX machine
to your Windows machine.

2. Import the mail into Netscape Communicator for Windows

3. Import the Netscape mail store files over to Outlook

This isn’t so important for stuff in your INBOX as it is for stuff in Sent-Mail, and other
user-defined folders. I had wanted to do this for some time, but never found an appropriate
conversion utility.
