Robert,

Thanks for the information.  I had an idea that you might be declaring a 
stream for every letter.  I've applied this to our system, and it's 
scheduled to run Sunday morning.  I'll let you know what I find.  Right 
now our mailbox backup takes almost 8 hours.  One stream, over gigabit.  
The total bytecount for the mailbox backup is about 48GB.
