Emilio thanks a lot for you advice , I will try this tonight when I can permit 
myself to down those services , ... 

I have one little question , after running the little script to remake a 
mbox_list format file I only have entries for the users in it ,not for their 
subfolders etc etc , ... will the reconstruct rebuild the indexes for their 
subfolders? 

Best Regards, 

Tijl
