Cyrus is *not* a flat file, though. There is a seperate file for
every message, *and* an index to those messages for searching and/or
displaying. Most of these ideas are not qmail's, though, they're derived
from other systems.
Although I do believe SCSI would be better here, this isn't really
a ``throw some hardware at it'' kind of problem problem.
