The problem is if you keep only the count of kBytes in a mailbox, what
do you do when you receive a message of 512 bytes? Do you not count it
at all, or do you count it as 1kB? If you keep actual bytes, you still
have the problem of it fitting in a 32-bit number, and if you round it
either way the quota will eventually be so wrong it is useless.
