Have you verified that the inode number changes?



no, I will check how to do this


'ls -li' is your friend.


Thanks, I have now used this to confirm that the inode number does not
change when postfix/local updates the mbox file. So the problem with
incrond lies elsewhere.

One thing to check is the sysctl parameter 'fs.inotify.max_user_watches' (which is what its name implies.) Some (EL-family, for example) distributions default to a low value (8K) which is a very easy limit to hit with a tool like incron that is designed to exploit inotify to its fullest.
