Also some policy servers exist that implement message quotas at the
authenticated user level, this is mostly for ISPs who provide MSA services
to consumers. Policy servers are not part of Postfix, the whole point that
the policy extension mechanism provides enough hooks for creative people
to implement interesting policies. This is not about DoS prevention,
more about limiting damage from spammers masquerading as consumers or
from zombie machines.
