best is to try before you need it! ;)

Just copy back the file to the uses mailspool. Since mails are numbered 
in ascending order no file may be overwriten. Check for ownership and 
rights!
Reconstruct the mailbox with "-rf".
reconstruct should discover the now new mailboxes (if you restore whole 
folders), if not you may create them with cyradm.
Sometime we create a new mailbox - like user.foo.restore - where we 
restore the file, so the user see what was restored and can move it to 
the place he wants it himself.
