database being a very generic term

probably not much more than that without hacking Cyrus deliver to deliver
to a user on a different machine. Multiple machines storing user data is
really the key, and is what every large mail hosting company I know of has
done (I've worked for two, and ironically they both started off by hacking
qmail).

If you really want a lot of users on a machine, it's a good idea to get
any actual mail transport agent off the machine, and delegate that to
other dedicated machines.
