As messages are processed by the system some tests are yes/no tests (virus infected / sending IP address black listed) and some are value tests. After a message has passed all the yes/no tests then the content of the message and the way it is put together is checked against 1000s of value tests. Each test has a value or weight and the message gets the sum total of all failed tests. It is this final total score that is compared against the various thresholds to decide the fate of a particular message. We call this our three strikes and you’re out testing.
