Corrupted mail account

[Jason Dixon]

We're running the default Cyrus IMAP server on an Apple Xserve  
(10.3.9).  One of our users corrupted two of their IMAP folders by  
attempting to move it to a new location, then back, apparently before  
the copy was complete.  Now, instead of something like this:

/Foo
/Bar

They now have this:

/Foo/Bar
/Bar

Where neither "Bar" folders are readable by the client.  At this  
point, I just want to delete them both and allow the user to recreate  
their IMAP structure and upload (they POP'd all their mail to local  
storage).  Unfortunately, when I delete their folders and do a  
reconstruct as the cyrus user, it recreates the broken structure.  I  
don't know much about Cyrus, but I'm guessing there's a master copy  
of this information stored in db.  How can I blow away this user's  
mail store and rebuild?

Thanks,
