SmartBounce has better than 97% bounce recognition without using VERP
(though it optionally supports VERP as well), so the human
intervention is pretty minimal -- and in many of those cases, there's
nothing for even a human to go on.
However, like all automated processes, it _does_ require a certain
amount of CPU and I/O ("The Killer"(tm)) for processing.
