If you store your mail messages in traditional unix mbox format then any new 
messages 
or deleted messages for one user will change the mbox file for that user and 
the 
backup will include all of that user's mail (since it is all in one file).

To get true incremental backups for user mailboxes you would need to use one of 
the 
formats that stores messages as individual files, like Maildir.

Is that the problem or do you already use Maildir format?
