It depends... if your setup is simple enough.. yes you could write a 
script to scan your folders and rewrite the text dump format of this 
file.  It also contains what imap partition the folder is on.. the 
owner.. and all permissions on the folder.  If you use a lot of shared 
mailboxes.. there is no other way to recover the permissions info that I 
know of.  Yes you could get by without it.. maybe.. but notice I didn't 
say it was impossible to rebuild this data.. only that it wasn't easily
