[horde] getting files back after server crash

[nick at collinson.fr]

My server crashed. I got almost everything back including pending  
messages in maildir and all is now working on a new server. However I  
had a number of folders and numerous e-mails stored with attachments  
in Horde and an address book. I tried restoring the databases in /var/ 
lib/mysql/horde but these archived messages and address book do not  
seem to be there. Where else can I look in the old servers backup  
data? Have I lost this data forever?
