If you need a list of mailboxes, you can probably get a pretty  
complete one with "strings mailboxes.db".  Minus anything that's  
really corrupted -- as opposed to corrupted meta-data.

Move mailboxes.db and the contents of the db directory out of the  
way.  Then, for each mailbox (derived either from the "strings"  
command or from the spool directories), run:

	reconstruct -r -f

The main problem that you might run into is that reconstruct isn't  
aggressive enough about reading sub directories.  So feeding a  
complete list to reconstruct (in which case you won't need -r) would  
be handy.
