[ale] Exporting M$ Express mail files (MacOS -> ???)

[johnmills at speakeasy.net (John Mills)]

ALErs -

The family iMac is about to move to another life and I need to capture my 
wife's Outlook Express e-mail files and address book for some other mail 
reader. If we go with some Linux box for her, what are the mail reader and 
export/import options for doing this? Does 'thunderbird' have a way to 
import M$ mail and addresses?

TIA.
