For those of you that know me, know that I'm a huge fan of Knoppix. Not so much because it's the best at this or that but because it is a very complete bootable live linux cd. I've been running one of my laptops exclusively off it for months.
Tonight... while looking for security tools I found this: Knoppix STD security tools distribution http://www.knoppix-std.org/. Which contains a few tools I never knew existed.
Here's one that caught my eye.
readdbx : convert Outlook Express .dbx files to mbox format
