Is there a Linux email program that acts like Outlook or uses its files?

Here's what I'm working with. My old windows XP computer was decommissioned so I can use it for other purposes, and the replacement I was using (also with XP) has since died. I'm now using a new computer running Suse Linux 12.2, and I have my hard drives from the Windows computers installed into it so I can use my files. That includes all the MS Outlook email saved data (.iaf and .dbx files).

Is there a Linux email program that will not just import (ie. copy) those old emails, but can actually make use of those Outlook email storage files if I set it to use that folder? I don't want to lose my old emails, want to continue using and updating the email storage files in case I revert back to using Outlook on a windows PC, and I greatly prefer to use POP mail to store the emails locally rather than using IMAP and keeping email stored on the server.

I have not found a way to make Thunderbird access those old files (or import them for that matter), and Kmail (KDE mail) will import them as a copy into its own storage folders but not directly access and use the old Outlook storage files. A search for email programs like this has turned up nothing.
