 I guess I don't understand what's wrong with a sequential naming system.
It seems to me that all you really want to do is divorce the file names
from the chronological ordering of the messages. That doesn't seem to
require hashes or longer filenames. As long as we keep a mapping between
filenames and the numbers used for the mbox or chronological sequence, and
don't use the filename sequence for anything other than guaranteeing filename
uniqueness (i.e. if we insert a message into the middle of an mbox, we
would create a filename with a number higher than the highest filename),
then we seem to get what you want without making filenames uglier and
without having to worry about how often the hash creates collisions.
