What I found is

1. /var/spool/imap/user/xxx exists
2. /var/spool/imap/user has several directories
3. All other directories except ABC are listed as folders under and are seen by IMAP clients.
4. ABC directory has subfolders like /var/spool/imap/user/xxx/ABC/1, 2  
3 etc and each of these subdirectories has cyrus.* files except ABC  
directory.  As you said, as ABC directory does not have cyrus.* files,  
reconstruct has failed to recognise it and hence its subdirectories.

Should I run reconstruct -r -f or cm and  
then run reconstruct -r -f

Sorry to bother you.  Thanks in advance.
