Remember, the number of mailboxes isn't as important as the number of 
concurrent connections.  The number of mailboxes just impacts the amount 
of storage, the number of concurrent connections impacts both the amount 
of memory and the bandwidth to the storage.  Unless you're doing a lot 
of SSL/TLS connections, the CPU is "relatively" unimportant.
